Abstract
The physical and mechanical properties of soil from the place of landsliding are studied in laboratory conditions. The problem is solved under the assumption that the landslide mass before and after landsliding remains unchanged. The value of the landslide mass is determined. By constructing various possible sliding surfaces and determining stability factor for each of them, the most dangerous sliding surface was found. To ensure the safety of residential settlements and other objects located at the base of landslide slopes, it is necessary to know the distance that the landslide will travel when fully unloaded. The distance of displacement of landslide masses in the horizontal section is determined.
