Interdisciplinární přístup při hodnocení stability horninového masivu postiženého svahovými deformacemi s využitím geofyzikálních metod

Abstract

The aim of the thesis is an interdisciplinary approach in the evaluation of the stability of a rock massif affected by slope deformations using geophysical methods. To achieve the goal, I am evaluating geophysical measurements at three locations. At the first location, it was necessary to verify the engineering geological and hydrogeological conditions of the area, assess the causes of the local landslide and propose a method of rehabilitation of the gas pipeline route for the future laying of the gas pipeline in the currently prepared route - the working lane. Drilling work could not be carried out on the site, and the preparation of the engineering geological profile for the stability calculation in the GEO5 program was more or less based on the results of electrical resistivity tomography, dynamic penetration and laboratory results. In the second location, there was an emergency situation, when the service road and recreational huts on the left bank of water reservoir Dolná Hodruša were broken by slope movements. The task was to verify the engineering geological and hydrogeological conditions of the territory, investigate the causes of the local landslide and to propose a method of rehabilitation. Drilling work, laboratory work, geophysical work, stability calculation and rehabilitation design were carried out at this location. At the third location, repeated geophysical measurements were carried out using electrical resistivity tomography (ERT), spontaneous polarization (SP), dipole electromagnetic profiling (DEMP), electromagnetic radiation (EMR) and one GPR measurement. In this chapter, I deal with the monitoring of slope deformation based on repeated geophysical measurements.
