The quantity slope stability assessment organization based on the engineering, geological and geophysical investigations analysis. The geomechanical slope’s models creation realized along stability assessment for slopes in natural conditions and in conditions of one estimated geological element soaking and thawing. Morgenstern-Price, Bishops and Janbu methods were the main in stability assessment. The estimation analysis allows concluding that there are two main mechanisms of sliding processes on the slope. In the first case, landslide dislocations occur in the embankment’s body. The second mechanism bases on the assumption of one estimated geological element soaking and thawing. In this case, sliding dislocations cover the whole embankment. The embankment’s displacement comes along frozen moistening loams (main straining horizon (MSH)). This main straining horizon is the base for made ground. In addition, displacement may occur because of infiltration the surface water along well-filtering macadam in warm period. The main sliding factors at the territory are significant relief energy, low strength properties of soils during it soaking and thawing, artificial cooperation. Fine probability sliding process activation predetermines the necessity of design and engineering protection measurements organization.
