This report describes the work carried out in the second year of the public contract Geological and geotechnical characterisation of the rock environment – PVP Bukov II. The\ncharacterisation and descriptive works are directly related to the excavation of the premises for the future underground laboratory. These include in particular: geological and geotechnical documentation of the faces and walls of the workings, petrographic, mineralogical and structural geological documentation, hydrogeological characterisation of the environment, as well as determination of the physical and mechanical properties of the rock mass in situ and in the laboratory, geophysical characterisation and monitoring of the seismic effects of blasting and hydrogeological monitoring. An important part of this report is preparation of the classification system used to describe the rock mass. The report also includes a brief overview of the work planned for the third year of the project.

Influence of the stress field on weathering and erosion of sandstone landforms
Řihošek, Jaroslav ; Bruthans, Jiří (advisor) ; Mikuláš, Radek (referee) ; Válek, Jan (referee)
The influence of mechanical stress on weathering and erosion has been overlooked in works focused on sandstone landforms formation, although stress has been shown to be a key factor in the formation of a number of different sandstone landforms recently. The main goal of the doctoral thesis is to understand the relationship between mechanical stress and weathering or erosion in the formation and development of sandstone landforms. The influence of mechanical stress on the mode of weathering and the rate of disintegration of the material forming historical monuments in Petra, Jordan was investigated on the site and on samples in laboratory. A negative exponential dependence has been proven between the speed of salt weathering and the magnitude of uniaxial compression of Petra sandstone samples. The role of mechanical stress as a mechanism controlling the formation and development of the shape of sandstone forms was further studied in rock overhangs, sandstone arcades and rock gates in the Czech Republic and the USA. The doctoral thesis presents and verifies a method using Střeleč sandstone as a natural analogue in physical models simulating weathering and erosion of cemented sandstone. These physical models usually take the form of a reduced initial shape of a sandstone object created in situ from...
Structure of apartment building
Řihošek, Jan ; Pulec, Vladimír (referee) ; Perla, Jan (advisor)
The diploma thesis deals with the design of the floor structure of an apartment building in two structural variants. The aim of the work is to find out the internal forces, design and check in two construction variants. Finite Element Method was used for calculation internal forces using 2D model for floor slab and 3D model of building in the Dlubal RFEM 5.24. The work also includes check of masonry walls.
Concrete slab roof of underground parking garage
Řihošek, Jan ; Strnad, Jiří (referee) ; Perla, Jan (advisor)
Bachelor thesis deals with the roofing of the underground parking garage with reinforced point-supported slab. The aim of the work is to find out the internal forces on reinforced slab for two of the construction variants, design and check one construction variants. The replacement frame method and Finite Element Method were used for calculation internal forces using 2D model in the Dlubal RFEM 5.17. The work also includes the design and check of one column.

This report summarises outline of a report for evaluation of the sites‘ suitability for the emplacement of a deep geological repository on the basis of the archive information and the geological survey conducted from surface.\nSites are evaluated according to the following criterion categories\n1. Geological characteristics of the site\n2. Hydrogeologic characteristics of the site\n3. Transport characteristics of the the site\n4. Site stability\n5. Factors, increasing probability of human intrusion into the site\n6. Acceptability of enginnered barrier properties under site conditions
Petrology and geochemistry of Devonian volcanic rocks in the southern part of the Šternberk-Horní Benešov Belt
Řihošek, Jaroslav ; Kachlík, Václav (advisor) ; Přichystal, Antonín (referee)
Šternberk-Horní Benešov belt (SHB) is built by Devonian and Lower Carboniferous rocks located between Culmian Eastern Jeseníky and Western Jeseníky nappes. As the SHP is located in the Low Jeseníky Mountains , it is a part of Rhenohercynian zone of European Variscides. The southern part of SHB is built by a volcanic complex of intrusive rocks, lavas and volcanoclastic rocks with intercalated beds of Stínava- Chabičov shales. Alkaline volcanism in Rhenohercynian zone was earlier interpreted as a result of extension in back-arc basin. Structural measurements of this study proved, that volcanosedimetary succession (situated north eventually northward) of Šternberk) is a tectonic slice. This slice was dragged out on the base of the Culmian greywacke nappe during the Variscan orogeny. Firstly the slice was thrusted northeastwards over the body of younger Culm greywacke. After that, the stack of nappes (including the Devonian volcanic rocks ) was sheared in dextral transpressional regime. The field works also indicated, that the Devonian vol- canic complex was tectonically separated from its stratigraphic footwall and hanging- wall. Volcanic rocks gradually built an elevation, eventually reaching the sea level. Anal- ysis of volcanic facies proved that the most of volcanoclastic rocks was deposited near...
