Securing of Foundation Pit in Brno for the Underground Garage at the Janáček Theatre
Zapletal, Adam ; Štefaňák, Jan (referee) ; Masopust, Jan (advisor)
The bachelor´s thesis deals with the sheeting construction real construction pit underground parking garage at the Janáček Theatre in Brno. It contains the description of the possible solutions to the appreciation of their advantages and disadvantages. The goal is to choose one of these methods based on evaluation of engineering-geological survey appropriate method to ensure that the construction pit. For this method to perform static analysis and process design documentation.

Foundation of new and redeveloped supports "Old Bridge" over the Danube in Bratislava
Korec, Michael ; Štefaňák, Jan (referee) ; Masopust, Jan (advisor)
The thesis is focused on the reconnstruction of the "Old Bridge“ in Bratislava. Part of the reconstruction is the foundations of a new pier and redevelopment of an existing pier. The introduction provides an overview of methods used for the foundations within the river and from there onwards, the most suitable method haas been selected. The piers foundation is designed in several variants, coupled with the drawings. In conclusion, the variants were compared and the most suitable one was selected.

Foundation of Bridge
Ščudla, Martin ; Štefaňák, Jan (referee) ; Masopust, Jan (advisor)
The thesis focuses on design of 5 - square bridge foundation in Ostrava Svinov including covering of construction pits. The bridge is founded on the groups of drilled large diameter piles. Design and assessment is realized in program GEO 5. The thesis is divided into 6 parts: introduction, geotechnical circumstances, concomitant report, static calculations, technical report and documentation.

Statistical analysis of the acceptance tests of ground anchors
Štefaňák, Jan ; Hrubešová,, Eva (referee) ; Záleský,, Jan (referee) ; Masopust, Jan (advisor)
The objective of dissertation is to find the approaches for processing the data extracted from the reports that document the performing of acceptance tests of ground anchors. The purpose of this activity is to allow further utilization of this data for designing practice. 795 test records were collected. It is essential for the correctness of analysis, that the whole anchor bond must be placed in homogeneous material. The records for anchors that don’t fulfilled this condition were removed. The set of 379 records of anchors installed in six different soil types during construction work in Czech Republic remained. All those anchors were tested according the demands of european standard ČSN EN 1537:2001, valid until 2013. The methodics based on the mathematical statistics, regression analysis and probability methods were compiled during solving the task defined above. The major result of data processing that was performed via methodics based on combination of mathematical statistics and probability simulation methods is the set of bond shear stress parameter values elaborated for variety of soil types. The regression model for determination of the force-displacement curve and the model predicting the creep behavior of loaded ground anchor were constructed, where the creep value is dependent on the tendon bond length, tendon free length and on the level of prestressing force. The description of full-scale experiment, whose results were used for verification of assumptions incorporated in relevant methodics, is included. The example of determining the probability of failure of anchored structure using the stochastic simulation technique is mentioned also, where the previously obtained results are used as input values for this calculation. Moreover, the software application serving for automatization of processes associated to conducting of the tests of ground anchors and to creating the test report is introduced.

Design of foundations for the production hall
Machů, Michal ; Glisníková, Věra (referee) ; Štefaňák, Jan (advisor)
The subject of this work is a proposal of foundation, followed by an assessment for a production hall. Options will be discussed and compared against each other. The premises are situated in an area where great layers of gravel are found. A project of shallow foundations, or more shallow foundations founding, will be performed according to Eurocode 7. Designing of geotechnical constructions which are based on given characteristic of presented soils. As a part of this work also is to describe a performing technological procedure of designed founding and an appropriate drawing documentation.
