Founding in region of Velké Bílovice
Moravčík, Martin ; Masopust, Jan (referee) ; Brdečková, Helena (advisor)
Bachelor's thesis got two parts. In teoretical part I examene geology and geomorfology of region Velké Bílovice. Half of practical part analyse laboratory samples that are taken from Velké Bílovice. I tested samples for physical and index properties and mechanical properties. Second half of practical part is design and assessment of gravity wall by EC 1997. Earth pressures are calculated by ČSN 73 0037. Geological conditions for gravity wall are calcareous clays from examined properties and loess by [5]. Assessment was controled with computer program GEO5.

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.

Posouzení velikosti jízdních odporů automobilu v závislosti na vybrané dopravní trase
MASOPUST, Jan
The main aim of the thesis is the analytical activity in relation to the running resistance, which are inherent in the type of used vehicles. The analysis aims to differentiate driving resistances and related technical and technological factors, which determine the size and possibilities of solutions to reduce driving resistances. Obtaining specific variables carried out by the analysis leads to the determination of driving resistances for selected vehicles, even depending on the total fuel consumption. The first part of the thesis is based on adequate and relevant literature focused on the analyzed subject taking into account factors such as the character of road transport, environment and electromobility. The practical part deals with the measurement of individual types of driving resistance on a selected sample of vehicles depending on the driving mode and the character of the transport route.

Utužení půdy jako důsledek činnosti zemědělské techniky
MASOPUST, Jan
This diploma work is dealing with the issue of compacted arable land made by agricultural equipment, in the Czech Republic. The first part of the thesis introduces factors that causes the compacted soil. Then, we are looking at the ways how to prevent the compaction or, on the contrary, how the undesired compaction can be removed or at least minimalized. This is analyzed in detail according to factors that may influence the process of the land compaction, such as the actual weight of the agricultural equipment kit combination, the choice of the correct tires and the economy of plant growing.
