ASSESSMENT OF DESTABILIZING FACTORS ON A POTENTIAL LANDSLIDE SLOPE IN SOFIA KETTLE – EXAMPLE FROM THE GERMAN VILLAGE AREA, BULGARIA
Proceeding of 1st International Conference on Environmental Protection and Disaster RISKs, 2020, DOI: https://doi.org/10.48365/ENVR-2020.1.38
In the present study, a specific sample area has been selected, where an assessment model is made for the stability of a slope subjected to anthropogenic impacts. A slope from the foot of the Lozenska mountain in the periphery of the Sofia kettle has been chosen as such an exemplary area, as part of the dangers arising in the Trans-Balkan valleys. Landslide processes as a result of anthropogenic impact often occur on the territory of the Sofia valley. The increased construction, the development of hard-to-reach terrains with large slopes, their undermining, the seismic impact and the low values of the strength-deformation parameters of the geological varieties building the respective terrains contribute to their occurrence. The deforestation, the loads with heavy embankments, the hydration, the inhomogeneity of the layers of the earth base have a strong destabilizing effect. The terrain in question is located in the southeastern part of the village of German, at the base of a steep 35 ÷ 49º slope. The paper presents the results of field and laboratory studies, analyzes of slope stability by the method of Felenius. The severity of the impact of the various destabilizing factors was assessed.
