Dubičná landslide - engineering geological mapping and Atterberg limits
Vavřich, Lukáš ; Jerman, Jan (advisor) ; Routner, Martina (referee)
This bachelor's thesis addresses the issue of slope deformations in the České Středohoří region and closely examines the landslide at the Dubičná site. In the late 1960s, significant slope deformations occurred here, endangering a railway embankment and the road beneath it. The landslide is situated in a geologically complex terrain where manifestations of Tertiary volcanism intersect with sediments from the Bohemian Cretaceous Basin. Due to the geological history, the broader vicinity of the studied area features numerous slope deformations with the potential to cause property damage and threaten human lives. Detailed field mapping was conducted in the landslide-prone area, resulting in the creation of an engineering-geological map of stability conditions. This map, utilizing modern remote sensing technologies, intricately depicts the progression, morphology, and shape of the landslide. Soil samples were also collected, and following prescribed laboratory procedures, their index properties were measured, including liquid limit and plastic limit moisture content. Based on the results of these measurements, the presence of a deformation zone within the landslide was estimated to be at a depth of approximately 5.5 meters.

ANALYSIS OF A SLOPE DEFORMATION OF THE D11 MOTORWAY CUT
Rotová, Petra ; Tábořík, Petr (advisor) ; Blahůt, Jan (referee)
This diploma thesis consists of a research and a practical part. The research part summarises the problem of slopes movements. The practical part deals with the determination of the slope deformation causes, at the 76th km of the D11 motorway. Causes determination was based on laboratory tests of soil samples taken from the disrupted motorway cut, made at PřF UK soil mechanics lab. Tests of grain size composition were done, plasticity of the L 26 sample was determined and critical strength of the reconstituted L26 and L27 samples was found out in the Translational apparatus box. Soils were categorized due to the according standards and the acquired data were evaluated. In the BricsCAD software, a well arranged locality situation and the slope deformation crosscut underlayed with the geophysical ERT cut were illustrated. In the GEO5 software, slope stability models were created using the Spencer Method of Slices. The slip surface and the groundwater level during the disruption were determined. The practical part also covers a proposal of a remediation appropriate for this deformation and it's modelling in GEO5. For the remediation, the slope stability level is determined. The work is based on the specialized literature, articles, research reports and standards. Powered by TCPDF (www.tcpdf.org)

Slope deformations in the Bohemian Paradise - research, typology and conditions of origin
Merlíčková, Soňa ; Hartvich, Filip (advisor) ; Blahůt, Jan (referee)
This thesis deals with occurrence, conditions and character of slope deformations in the Protected landscape area (CHKO) Český ráj. This area is typically formed by sandstones, marls and claystones. Together with tectonic structures and lateral erosion of the Jizera River, they form suitable conditions for slope movements such as rockfall, sliding etc. With help extensive use of the scientific literature, character of study area as well as general conditions for the development of slope movements were described, and their typological classification was established. Next part of the thesis includes the chapters on the methods of research, and a description of the preliminary field research of the model localities. Furthermore, an analysis of causes of the slope movements using the data on climate from the stations of Czech hydro-meteorological institute was performed. Finally, the results are discussed with the referenced sources and conclusions to the topic are formulated. Keywords: CHKO Český ráj, slope movements, slope deformations, tectonics, lateral erosion, land-slide, rockfall, Lužický fault
