Assessment of the factors affecting slope stability in the southern part of the Sofia Kettle

A specific sample area was selected, where an assessment model made for the stability of a slope subjected to anthropogenic impacts. hillside zone from foot Vitosha and Lozen mountains in southern periphery Sofia Kettle chosen as exemplary part hazards arising Trans-Balkan valleys. The impact on their studied three particular slopes. study is about 1.25 km2 has maximum distance up 3.80 km between Landslide processes resulting often occur territory Valley. rise construction, development hard-to-reach terrains with steep slopes, undercutting, seismic low values strength-deformation parameters geological varieties building respective contribute occurrence. deforestation, loads heavy embankments, hydration inhomogeneity layers earth base have strong destabilizing effect. paper presents results field laboratory tests analyses by method Fellenius. severity various factors assessed.
