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.
