Finite Element Limit Analysis method for stability evaluation of geotechnical structures
Juračka, Petr ; Koudela, Pavel (referee) ; Chalmovský, Juraj (advisor)
The thesis consists of theoretical and practical parts. For the practical part it was necessary to state the theoretical assumptions including the definition of the external degree of stability. Furthermore, the principles of limit analysis and its combination with the finite element method. In the same essence, the method of shear strength reduction. At its conclusion, it was necessary to introduce the issue of associated and non-associated plasticity in numerical stability calculations. Then it moved to the practical part, where the sequence and methodology of performing the comparative calculations were presented, which were selected as the so-called benchmark problems for the thesis. In the next chapter, the results of the individual examples were already presented with their subsequent analysis. Finally, the application of the FELA method was shown on a real boundary problem, namely on an earthfill dam within the Vlachovice dam project.

The Design of Nedašova Lhota Landslide Securing
Janík, Michal ; Polášková, Alena (referee) ; Glisníková, Věra (advisor)
The thesis called The Design of Nedašova Lhota Landslide Securing concentrates on the basic analysis of the problems connected with landslides and safety factors needed for the slopes stability. At the same time it presents a concrete solution to the given practical task, where the slope stability, the causes leading to the landslide and the subsequent redevelopment in view of financial requirements are discussed.

Engineering geological survey evaluation of area affected by lanslides in Budkovice
Prechtlová, Kateřina ; Paseka, Antonín (referee) ; Erbenová, Alexandra (advisor)
This Thesis deals with evaluation of engineer-geological survey of area affected by landslides near Budkovice. The area of interest is situated in the south part of Boskovická brázda on the left bank of the river Rokytná. The Thesis first outlines the problems of slope movements in general: why it’s appropriate to study them, what factors play role in their creation, what areas are prone to their creation, how to proceed with engineer-geological survey and how the slope stability is solved. Next itfocuses on the above mentioned landslide in village Budkovice. Geology and hydrogeology of the area of interest were studied. Carried out survey works were summarized. I became familiar with their results and outputs.Friction angle of the residual strength on the slip plane was calculated using Pettersson’s method, it’s value was 11,27°. Simple geological cuts though the slope area and calculation cut were made. Groundwater level was measured on the preserved drill holes and it was compared with former values.
