Optimization variant of the shear strength reduction method and its usage for stability of embankments with unconfined seepage
(Elsevier, 2023) Sysala, Stanislav; Tschuchnigg, Franz; Hrubešová, Eva; Michalec, Zdeněk
In this paper, an optimization variant of the shear strength reduction method is introduced and used for the solution of embankment stability problems with unconfined seepage. The optimization framework is based on approximations of non-associated Mohr–Coulomb plastic models with associated ones, especially by using various Davis’ approaches. Next, the finite element method is considered and mesh adaptive solution concepts are developed for both the unconfined seepage and stability problems. In-house codes in Matlab are used for their implementation. Finally, two numerical examples inspired by geotechnical practice are investigated in order to demonstrate the accuracy of the optimization framework and to evaluate three different Davis’ approaches. The results are compared with commercial codes in Plaxis and Comsol Multiphysics.
Numerical simulation of heat recovery from asphalt pavement in Finnish climate conditions
(Elsevier, 2023) Songok, Joel; Mäkiranta, Anne; Rapantová, Naďa; Pospíšil, Pavel; Martinkauppi, Birgitta
A 3-dimensional mathematical model of asphalt pavement system was developed, based on the fundamental energy balance, to calculate temperatures beneath asphalt surface using hourly measured solar radiation, air temperature and wind velocity data. The modelling was conducted to predict the heat retention under the asphalt surface to seek an optimum position of pipe tubing to maximise the heat extraction considering the Nordic winter conditions for future infrastructure projects. The model results show good agreement with the experimental results conducted in a span of three months (June–Sept) notwithstanding the simplification of the model i.e. thermal properties unaffected by changing moisture content, perfect contact between different layers and homogeneous and isotropic thermal properties of materials (asphalt, sand and gravel). The findings indicated that the positioning of the heat extraction tubes under the asphalt layer will be dictated by the application. For heat extraction, pipes closer to the surface are ideal for maximal heat absorption during summer, however, in winter the outer temperature may effect properties the pipes. Parameters including pipe diameter, positioning of the pipes and flow rate were analysed. Temperature increase of up to 10 ◦C gain was observed for piping closer to the asphalt layer and 6 ◦C for pipes position at deeper from the asphalt layer. This model could be used in future to optimise critical variables for successful implementation of asphalt heating concepts.
Influence of vibration and ground deformation on historic structures: Case study
(Technická univerzita Košice, Fakulta baníctva, ekológie, riadenia a geotechnológií, 2022) Kaláb, Zdeněk; Ścigała, Roman; Strzałkowski, Piotr
When discussing historic structures, a significant problem is how to preserve and protect these structures. The presented paper deals with some issues of the unfavourable impact of industrial activity on some historic structures. Long-term influences from the industrial activity are one of the common sources of damage observed in these structures. Due to the size and volume of such structures, they are characterized by very low resistance to vibration and ground deformations. At the same time, the high cultural and material value of historic structures necessitates their costly protection and repair. Knowing the origin of problems, one may take proper actions to protect them. This paper discusses two important types of impact typical for industrial areas, especially affected by mining, seismically induced vibrations and continuous ground deformations from underground extraction. The presented discussion is based on the case study examples of historical sites located in some industrial areas in the Czech Republic and Poland. They point to different sources of damage to those structures that may arise as well as a combined effect of mining-induced seismic events and land subsidence. The medieval Jeroným Mine represents an underground structure loaded with natural and technical seismicity. The paper also includes a short overview of the process of seismic loading evaluation and basic information about historic structures with respect to seismic standards and land surface subsidence caused by underground mining.
Multi-GNSS positioning for landslide monitoring: A case study at the Recica landslide
(Akademie věd České republiky, Ústav struktury a mechaniky hornin, 2022) Li, Weiguo; Kačmařík, Michal; Pospíšil, Pavel
Global Navigation Satellite System (GNSS) positioning has characteristics of simple operation, high efficiency and high precision technique for landslide surface monitoring. In recent years, finalization of modern GNSS systems Galileo and BeiDou has brought a possibility of multi-GNSS positioning. The paper focuses on evaluation of possible benefits of multi-GNSS constellations in landslide monitoring. While simulating observational conditions of selected Recica landslide in the Czech Republic, one-month data from well-established permanent GNSS reference stations were processed. Besides various constellation combinations, differential and Precise Point Positioning techniques, observation data lengths and observation sampling intervals were evaluated. Based on the results, using a combination of GPS and GLONASS, or GPS, GLONASS and Galileo systems can be recommended, together with a static differential technique and observation periods for data collection exceeding eight hours. In the last step, data from GNSS repetitive campaigns realized at the Recica landslide during two years were processed with optimal setup and obtained displacement results were compared to standard geotechnical measurements.
Comparative in situ study of dynamic load generated by gravel piles measured by a fiber-optic interferometer
(MDPI, 2022) Stolárik, Martin; Kepák, Stanislav; Pinka, Miroslav; Čubík, Jakub; Nedoma, Jan
Currently, all the technology used for seismic monitoring is based on sensors in the electrical domain. There are, however, other physical principles that may enable and fully replace existing devices in the future. This paper introduces one of these approaches, namely the field of fiber optics, which has great potential to be fully applied in the field of vibration measurement. The proposed solution uses a Michelson fiber-optic interferometer designed without polarization fading and with an operationally passive demodulation technique using three mutually phase-shifted optical outputs. Standard instrumentation commonly used in the field of seismic monitoring in geotechnical engineering was used as a reference. Comparative measurements were carried out during the implementation of gravel piles, which represents a significant source of vibration. For the correlation of the data obtained, the linear dependence previously verified in laboratory measurements was used. The presented results show that the correlation is also highly favorable (correlation coefficient in excess of 0.9) from the values measured in situ, with an average deviation for the oscillation velocity amplitude of the optical sensor not exceeding 0.0052.
Natural radioactivity of rocks from the historic Jeroným Mine in the Czech Republic
(Springer Nature, 2021) Malczewski, Dariusz; Dziurowicz, Maria; Kaláb, Zdeněk; Rösnerová, Markéta
This study reports the natural radioactivity of characteristic rocks found in the historic Jeronym Mine of the Czech Republic as measured under the laboratory conditions. The rocks analyzed included granites and schists weathered to varying degrees and collected from different levels of the underground workings of the Jeronym Mine. The mine itself has been subject to metal extraction (mainly tin and tungsten) since the sixteenth century and has recently been developed as a cultural and scientific attraction open to the schema_dspacedb. Activity concentrations of K-40, Th-232 and U-238 were measured from nine rock samples using gamma-ray spectrometry. The activity concentrations of K-40 varied from 595 Bq kg(-1) to 1244 Bq kg(-1), while Th-232 varied from 25 Bq kg(-1) to 55 Bq kg(-1). The activities associated with U-238 ranged from 46 Bq kg(-1) to 386 Bq kg(-1). The measured activities were used to estimate two radiation hazard indices typically applied to building materials, the activity concentration index I and the external hazard index H-ex. Mean respective values of 1.02 and 0.77 for I and H-ex indicate that the rocks found in the Jeronym Mine meet radiological safety standards for building materials and do not pose a risk to potential tourists and staff.
Optimization and variational principles for the shear strength reduction method
(Wiley, 2021) Sysala, Stanislav; Hrubešová, Eva; Michalec, Zdeněk; Tschuchnigg, Franz
In this paper, a modified shear strength reduction method (MSSR) and its optimization variant (OPT-MSSR) are suggested. The idea of MSSR is to approximate the standard shear strength reduction to be more stable and rigorous from the numerical point of view. The MSSR method consists of a simplified associated elasto-plastic model completed by the strength reduction depending on the dilatancy angle. Three Davis' modifications suggested by Tschuchnigg et al. (2015) are interpreted as special cases of MSSR and their factors of safety are compared. The OPT-MSSR method is derived from MSSR on the basis of rigid plastic assumption, similarly as in limit analysis. Using the variational approach, the duality between the static and kinematic principles of OPT-MSSR is shown. The numerical solution of OPT-MSRR is obtained by performing a regularization method in combination with the finite element method, mesh adaptivity and a damped Newton method. In-house codes (Matlab) are used for the implementation of this solution concept. Finally, two slope stability problems are considered, one of which follows from analysis of a real slope. The softwares packages Plaxis and Comsol Multiphysics are used for comparison of the results.
Research into the influence of subsoil on sulphates, nitrates and chlorides accumulated in renovation plasters used for rehabilitation of monuments in the Czech Republic
(Elsevier, 2021) Peřinková, Martina; Dlábiková, Ivona; Pospíšil, Pavel; Bílek, Vlastimil
Degradation of historical masonry and plasters is often caused by external conditions; the presented research focused on salts originating from subsoils. The content of salts: Sulphates, Nitrates and Chlorides was analysed from plasters on 5 chosen historic buildings before and after the renovation in this paper. The samples were collected three times between 1998-2018. In some cases, the Sulphates were still present or even with a higher content after the renovation in comparison with the state before renovation. That can be caused by many factors from environment and this work focused on source from the subsoil. To understand better geological background the borehole data around each object were studied. According boreholes were buildings divided in two groups: on clayey subsoil and building on subsoil without clay. By Kruskal-Wallis test was proved, that the Sulphates content in plasters was constant before and after the renovation on clayey subsoils, it didnt ' changed in a time. On subsoils without clay (mainly silty to sandy soils) the content of Sulphates declined after the renovation, what was proved by regression analyse on 95% confidence level.
New methods to seismic monitoring: Laboratory comparative study of Michelson fiber-optic interferometer and pneumatic measurement systems
(MDPI, 2021) Stolárik, Martin; Nedoma, Jan; Martinek, Radek; Kepák, Stanislav; Hrubešová, Eva; Pinka, Miroslav; Kolařík, Jakub
New possibilities of vibration monitoring can be found in completely different physical approaches, where all measuring technology is currently based on sensors in the electrical domain. This paper presents two different promising alternative approaches to vibration measurement, specifically in the field of fiber-optics and pneumatic sensors. The proposed solution uses a Michelson fiber-optic interferometer designed without polarization fading and with operationally passive demodulation technique using three mutually phase-shifted optical outputs. Experimentally developed sensor systems for the registration of anthropogenic seismic phenomena were complemented by standard instrumentation for measuring seismicity used as a standard. The measurement was performed under simplified conditions using a calibrated stroke as a source of dynamic loading. In addition to alternative systems, the paper also presents the results of recalculation of the measured values in a time domain and basic relationships for the conversion to basic units derived from the SI (International System of Units) system and used internationally in the field of seismic engineering. The results presented demonstrate that even systems operating on a different physical principle have great potential to replace the existing seismic devices. The correlation coefficients for both sensory devices were high (above 0.9) and the average deviations from the measured values of the amplitude of the oscillation velocity did not exceed the value of 0.02, neither with the fiber-optic or pneumatic sensor.
Research of the behavior of clay materials with double porosity
(MDPI, 2021) Lahuta, Hynek; Pais, Luis Andrade
This contribution presents results from a series of compression and undrained triaxial tests to study the mechanical behavior of dump clay from the north of Bohemia. The use of these materials as a foundation for construction can't be achieved without the adoption of some precautions. This comes from embankment, formed by digging the ground (altered claystone), up to the level of coal mining which is in a sub horizontal stratigraphic layer. A potential static liquefaction behavior was observed in undrained tests for high confinement stress. A structural collapse was noticed with the results obtained in the triaxial test. This collapse is characterized by an unexpected large decrease in deviator and mean effective stress. The soils formed have strength properties that are potentially dangerous. These concepts can improve the use of these kinds of soils in geotechnical engineering work. It continues and expands the results obtained in previous research, especially the future problematic use of these materials as the foundation soil for line or building structures.
Numerical simulation of the interaction between fibre concrete slab and subsoil — The impact of selected determining factors
(MDPI, 2020) Ďuriš, Lukáš; Hrubešová, Eva
Shape and material optimization of building structures, including reducing the amount of concrete used, are very important aspects in sustainable construction. Numerical modelling is currently used very effectively to design optimized and sustainable structures, including their interaction with the surrounding rock environment. This paper is focused on the three selected factors of numerical modelling of fibre concrete slab and subsoil interaction: (1) the constitutive model of fibre concrete slab, (2) deformational and strength characteristics of subsoil, (3) effect of interface elements. The specialized geotechnical software Midas GTS NX, based on the finite element method, was used for the modelling of this task. Numerical results were compared with the experimental measurement of vertical displacements on the upper surface of slab. In the presented study, three constitutive models of slab recommended in MIDAS GTS NX code for modelling concrete behaviour (elastic, Mohr-Coulomb and Drucker-Prager) were applied. In addition, the sensitivity analysis with respect to the deformational and strength characteristics of subsoil was performed. The numerical study also presents the effect of the interface elements application on the slab behaviour. The numerical results of maximum vertical displacements based on the Drucker-Prager and elastic model underestimated both the experimental results and numerical results based on the Mohr-Coulomb model. From the qualitative point of view (shape of deflection curve), the numerical simulation showed the better agreement of the Mohr-Coulomb constitutive model with the experimental measurements in comparison with the other two investigated constitutive models. The performed parametric study documented that reduction of the strength and deformational characteristics of subsoil leads to the increase of maximum vertical displacements in the centre of slab, but the experimentally measured deflection curve, including uplift of slab and gapping occurrence between the slab and subsoil, was not achieved without the interface application.
Variability of seismic loading over the surface of a concrete slab in interaction with the subsoil
(MDPI, 2020) Stolárik, Martin; Pinka, Miroslav; Nedoma, Jan; Fridrich, Michael
This article is aimed at the analysis of the behavior of a fiber-reinforced concrete slab in contact with subsoil during dynamic loading in close proximity. The properties of such slabs are important for evaluating their dynamic response, though the properties of the subsoil environment through which the vibrations propagate must also be taken into account. The analysis itself was performed on the basis of the results obtained from experimental measurements during seismic excitation with a calibrated impact. There were three concrete slabs tested, with varying amounts of fiber. The standard Vistec seismic instrumentation was used for measuring the dynamic response. The results of the experiment were processed in both the amplitude and frequency domains, and a graphic comparison in the waveform and frequency fields was made. The results acquired from this experimental research may support a more objective approach during the evaluation of dynamic impacts ranging from anthropogenic impacts to building structures.
Mohajerani method: Tool for determining the liquid limit of soils using fall cone test results with strong correlation with the Casagrande test
(Elsevier, 2020) Hrubešová, Eva; Luňáčková, Barbara; Mohyla, Marek
The European Standard EN ISO 17892-12:2018 describes the means of determining the liquid limit (LL) of soils using two independent test methods: the Casagrande percussion cup and fall cone test. The first method is characterized mainly by its universality and the second by its simplicity. However, these two methods are known to provide different results. The higher the LL, the greater is the difference between the results. In 2019, Shimobe and Spagnoli established a correlation between the Casagrande and fall cone tests for soils with LL < 150%, based on an analysis of over 100 experimental datasets. However, further studies are required for soils with LL > 150%. Mohajerani method, which combines the universality of the former method and the simplicity of the latter, is applicable for such soils. The main objective of the study was to apply the Mohajerani method to determine the LLs based on fall cone test results and to compare them with those of the Casagrande test (soft base), with focus on soils with LL > 150%. The experimental results showed that for high plasticity soil (containing bentonite, etc.), the differences in the LL between the Casagrande and fall cone tests are significant (ab to relative ratio 30%), and some modification of the fall cone test evaluation is required. This study confirmed excellent agreement between the LL evaluated using the Mohajerani method (i.e., modification of the fall cone test evaluation) and that obtained from the Casagrande test, even for soils with higher LLs. Furthermore, the fall cone test results were used to determine the plastic limit (PL) for those soils with LLs within 20-50% for which the Casagrande LL and standard fall cone LL were correlated (where the latter was not modified by the Mohajerani method). Determination of the PL for these types of soils via the fall cone test results offers credible results comparable to those of the standard thread rolling test.
Approach for optimisation of tunnel lining design
(MDPI, 2020) Mohyla, Marek; Vojtasík, Karel; Hrubešová, Eva; Stolárik, Martin; Nedoma, Jan; Pinka, Miroslav
This paper presents an approach that enables the specific characteristics of a primary tunnel lining implemented using numerical modelling to be taken into account during its design. According to the fundamental principles of the New Austrian Tunnelling Method, the primary lining undergoes time-dependent deformation, which is determined by its design. The main design element is shotcrete, which, shortly after its application, interacts with the surrounding rock mass and steel arch frame. The primary lining ensures the equilibrium stress-strain state of "rock mass-tunnel lining" during excavation. The structural interaction varies depending on the hardening of the shotcrete, the rheological properties of the rock mass, and other factors. The proposed approach uses the Homogenisation software application, which was developed by the Faculty of Civil Engineering at the Department of Geotechnics and Underground Engineering of the VSB-Technical University of Ostrava. This software allows the heterogeneous structure of the lining to be considered by replacing it with a homogenous structure. The parameters of the homogeneous primary lining, which take into account the steel reinforcement elements and the time-dependent property of the shotcrete, are included in numerical models.
Hydrogeochemical characteristics of the groundwater in the quaternary aquifer of western fringes of El-Minia Governorate, Egypt using an integration of geochemical modeling and geo-statistical techniques
(Desalination Publications, 2020) Ismail, Esam; Zaki, Rafat; Rapantová, Naďa; Ličbinská, Monika; Sharawi, Haiaa
Groundwater is a very important source of drinking and irrigation water especially in areas with little to no surface water sources. In the western desert of Egypt, groundwater acts as the main source of irrigation in the new reclamation project. The authors of the article used major constituents and trace elements chemistry as well as bacteriological and biological water analysis to assess the hydrogeochemical characteristics in the western bank of the River Nile, West El-Minia District. In order to fulfill the scope of work for this study, 88 groundwater samples were collected from the Pleistocene aquifer which represents the main aquifer in the study area. The groundwater samples were analyzed for pH, electrical conductivity (EC), total dissolved solids (TDS), major cations (Ca2+, Mg2+, Na-, K+), major anions (HCO3-, SO42- and Cl-) and trace metals (Mn, Cu, Pb, Zn, Ni, Co, As, Hg, Se, Al, Cd, Cr, B, and Fe). Microbiological and microscopic studies of the collected water samples were carried out to determine the micro-organisms' in order to confirm the safety of the water for human consumption. Also, statistical analysis and hydrogeochemical modeling were used to interpret the collected data. The study revealed that in all the collected water samples, alkaline earth metals have values higher than alkalies and are of meteoric origin. The groundwater chemistry is mainly controlled by rock weathering with a secondary contribution from anthropogenic sources. Forty-nine percent (49%) of analyzed water samples have trace constituents above the recommended limits for water use for drinking and irrigation purposes. The highest linear correlation was shown between TDS and EC, HCO3, Na+, Ca2+ and Mg2+, all macro-components and chlorides, between boron and chrome, as well as cobalt and lead. All sampled waters were classified as Ca-HCO3 water type and calcite precipitate in all collected water samples.
Alternative approaches to measurement of ground vibrations due to the vibratory roller: A pilot study
(MDPI, 2019) Nedoma, Jan; Stolárik, Martin; Kepák, Stanislav; Pinka, Miroslav; Martinek, Radek; Frnda, Jaroslav; Fridrich, Michael
At present, one of the primary tasks of the construction industry is to build transport infrastructure. This concerns both the construction of new bypasses of towns and the repair of existing roads, which are damaged by congestion, especially by freight transport. Whether it is a new building or a reconstruction, it is always very important to choose a suitable method of subsoil treatment. One of the most commonly used methods for soil treatment is currently compaction using vibratory rollers. This method is very effective both in terms of results and due to its low financial demands compared to other methods. Vibration is transmitted to the surrounding rock environment when compacting the subsoil using vibratory rollers. Although the intensity of these vibrations is not as pronounced as in other methods of subsoil treatment, such vibrations can have a significant effect, for example during compaction in urban areas or in an area with the presence of historical objects. Therefore, it is very advisable to monitor the effect of these vibrations on the environment during construction. This paper brings an original experimental comparative study of standard seismic instrumentation with a developed interferometric sensor for the field of monitoring vibrations generated during compaction of subsoil using vibrating rollers. The paper presents time and frequency domain results, as well as attenuation curves, which represent real attenuation of vibrations in a given rock environment. The results presented here show that a system operating on a different physical principle from the one used at present has the potential to replace the existing, very expensive, seismic equipment.
The effect of soil grain size on the deformation properties of reinforced geocell layers
(České vysoké učení technické v Praze, 2019) Luňáčková, Barbara; Mohyla, Marek; Pinka, Miroslav
The effect of backfill material grading on the behaviour of geocell reinforced layers was experimentally investigated in this study. A series of loading tests were performed on a model with geocell reinforced and unreinforced layers. Five types of crushed aggregates were used as backfill materials in the experiment. The results showed that geocell reinforcement increased the deformation parameters. The rate of increase of the deformation characteristics depended on the backfill material grading.
Alternative approaches to vibration measurement due to the blasting operation: A pilot study
(MDPI, 2019) Kepák, Stanislav; Stolárik, Martin; Nedoma, Jan; Martinek, Radek; Kolařík, Jakub; Pinka, Miroslav
As the infrastructure grows, space on the surface in the urban area is diminishing, and the view of the builders is increasingly moving underground. Implementation of underground structures, however, presents a number of problems during construction. One of the primary side effects of tunnel excavation is vibration. These vibrations need to be monitored for potential damage to structures on the surface, and this monitoring is an integral part of any such structure. This paper brings an original pilot comparative study of standard seismic instrumentation with experimentally developed fiber-optic interferometric and acoustic systems for the purpose of monitoring vibration caused by the blasting operation. The results presented show that systems operating on physical principles (other than those previously used) have the potential to be an alternative that will replace the existing costly seismic equipment. The paper presents waveform images and frequency spectra from experimental measurements of the dynamic response of the rock environment, due to blasting operation performed shallowly during the tunnel excavation of a sewer collector. In the time and frequency domain, there is, by comparison, significant agreement both in the character of the waveform images (recording length, blasting operation timing) and in the spectra (bandwidth, dominant maxima).
Ground-borne vibration due to construction works with respect to brownfield areas
(MDPI, 2019) Stolárik, Martin; Pinka, Miroslav; Nedoma, Jan
Ground-borne vibration caused by mechanized construction works is the most common problem in built-up areas in general. In post-industrial cities, there are many building facilities in the category of brownfields. Parts of these buildings are often technically and culturally valuable buildings with varying degrees of decay. These are very susceptible to vibrations. The revitalization of brownfield areas employs a wide range of works and practices, among which are those that have adverse effects in the form of vibrations and shocks. This paper presents a theoretical study and original results concerning the seismic load on historical and dilapidated buildings in brownfield areas due to the ground-borne vibration caused by mechanized construction works. Original data from seismic measurements are related to the post-industrial Ostrava agglomeration, in the area of one of the biggest successfully revitalized brownfields in Central Europe. All measurements were evaluated in terms of both amplitude and frequency. The results of all measurements were processed in the form of attenuation curves.
