Retaining Walls
Pospíšil, Jan ; Boštík, Jiří (referee) ; Glisníková, Věra (advisor)
The objective of thesis is to create a comprehensive overwiew of the most commonly used retaining walls in the Czech Republic and to characterize their properties, method of assessment, advantages, disadvantages or causes of failures. Based on these findings will be designed selected type of retaining wall in Rebešovice.

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.

Measurement of stiffness at small strains during oedometer test and detailed interpretation of output waves
Havlíček, Jaroslav ; Koudela, Pavel (referee) ; Chalmovský, Juraj (advisor)
This thesis has a theoretical and a practical part. The first part contains theoretical introduction to the phenomenon of increased stiffness at very small strains and possibilities of its practical applications. The available methods for evaluating initial shear modulus tests are described below. Increased attention is paid to the method of evaluation of test data in the frequency domain using the Fourier transform. The last chapter in this part describes an algorithm designed for automatic evaluation of measurements in the frequency domain. The practical part deals with measurement and evaluation of initial shear modulus for Brno clay as a function of vertical stress in oedometric test. Firstly, a device is presented that allows the extension of the oedometric test with sensors for measuring initial shear modulus of soil. This device was designed for the test in this thesis. Subsequently, the test plan is described including description of all soil samples. In this thesis, several types of soil samples from a single site were tested. Next, the results of the individual tests are evaluated by the selected methods. Examples are used for showing the differences in evaluation of the same data by other methods. At the end, the results of the individual tests for all sample types are compared with each other and with data from literature.

The Analysis of Slope Stability in Difficult Geotechnical Conditions
Wetterová, Alice ; Lacina, Jaroslav (referee) ; Glisníková, Věra (advisor)
Aim of the diploma thesis is design elements of slope stabilization in accordance with the planned highway D3 in Slovakia section of Cadca, Bukov - Svrčinovec and relocation of a local road. Objective subject is situated on the slopes of Cadca. In diploma thesis is an analysis of the area with the proposed stabilizing elements in the 5 GEO FEM, their assessment, including determining the overall stability of the territory according to the degree of safety.

Analysis of performance of embankment constructed on subsoil improved by vertical drains
Kováč, Vladimír ; Miča, Lumír (referee) ; Chalmovský, Juraj (advisor)
The thesis deals with the back analysis of the instrumentated embankment on the subsoil, improved by prefabricated vertical drains. The first part is devoted to the theory of consolidation calculation. Furthermore, the author deals with a parametric study of the analytical calculation of prefabricated drains and the comparsion of the analytical and numerical solution. The last and the largest part of the work is a back analysis of the embankment which was built as a part of the subsoil improvement near the Suez Canal in Egypt by Keller GmbH.
