On the fixing and anchoring technology
Klein, Adam ; Kouřil, Karel (referee) ; Píška, Miroslav (advisor)
Bachelor thesis is focused on practical analysis of used anchor elements for particular areas. The beginning of the thesis devides anchor and fastening elements based on its construction as well as information meant for correct element proposal, especially in civil engineering. The thesis also mentiones couple of examples where anchoring makes the most important part for the overall functionality. Second part of the bachelor thesis focuses on materials and element’s surface adjustment, espacially against corrosion. In conclusion, there are mentioned examples of testings, whether for the particular element’s resistance to corrosion or for its cohesiveness in anchored bedrock.

Analysis of Parameters of the Injection Curtain in the Bedrock of the Vlčia Dolina Dam
Václavik, Patrik
Goal of this article is to analyze the parameters of the curtain grouting (CG) in the bedrock of the Vlčia Dolina dam, using the modern criteria for water pressure tests (WPT). The input data for the evaluation of the CG were taken from the results of the water pressure tests. When designing the parameters of the injection screen at the time of its construction, Lugeons criteria were used. At present, 70 years after the start of operation of the waterworks, newer criteria are used for the design of parameters (depth). The purpose of the presented article is mainly the analysis of the suitability of the use of the criteria (Jähde, Verfel, Houlsby) in the conditions of the bedrock of the Vlčia Dolina dam. The finite element method (FEM) was used to find optimal depth of the curtain grouting.

Methods for determining the depth of impermeable bedrock as a basis for hydrological reserch.
DUBEC, Štěpán
This thesis is focused on the description of subsurface structures in the area of interest - Kopaninský stream catchment - and consequently the most accurate interpretation depth of bedrocks. Geophysical multicable metod (ERT ?electric resistivity tomography?) was selected for field measurements. This method of geophysical survey provides the information on subsurface structures, verifies hypotheses and brings new information on the lithological and structural conditions below the surface. ERT measurements were performed automatically by geoelectrical ARES device in combination with intelligent electrodes. The data obtained by field measurements were plotted in the form of resistive sections (using RES2DINV software) which were used for interpretation. The result of this work is to determine the depth of bedrocks and should serve as a data input for MIKE SHE hydrological modeling.
