Abstract
Failure process and large scale material movement of landslide, caused by the presence of a sand lens in the undercut clayey slope, at Ubilci (Yugoslavia) is analyzed by the Extended Distinct Element Method (EDEM). Magnitude of the landslide process caused by changeable clay cohesion during dry and wet season is studied for two hypothetical values of clay cohesion, high and low. The numerical results obtained are in good agreement with the failure surface and the shape of the slope of a real case landslide occurred at Ubilci (Yugoslavia).
