Zhodnocení měření přesné inklinometrie na vybraných svahových deformacích

Abstract

The main objective of this thesis was an assessment of accurate inclinometric measurement at an important slope deformation of Chmiňany, which threatens the D1 highway. This measurement was undertaken in cooperation with the Department of Engineering Geology of the Faculty of Natural Sciences of the Comenius University in Bratislava. A complex geological and geotechnical monitoring takes place at the above mentioned slope deformation. Partial objective of this thesis was to present an overview of the present state of engineering-geological conditions. A complex of slope deformations is located in Chmiňany municipal area. The topics of this thesis are the main dominant slope deformations, which were named as Chmiňany slope deformation. Other slope deformations are located here as well, such as Chmiňany Nová Ves slope deformation, however their assessment is not a topic of this thesis. The description of an accurate inclinometric measurement methodology with detailed instructions for measurement are also a partial objective of this thesis. Within the scope of the thesis an indicative stability calculations were done at the chosen profiles from 6-th and 7-th cross sections. Its outcomes are only indicative due to a lack of accurate information on geological structure and geotechnical parameters. The outcomes of inclinometric measurements were compared with the outcomes of computational solution of the slope stability. The calculation was done by GEO 5 programme made by the FINE company. Optimal computational model was found by making tens of calculations so that the outcomes of the calculations would best fit the ascertained shape of the landslide and the outcomes of inclinometric measurements.
