- Abstract
- The description of new theoretical solutions of forming a strain and stress state in the soil massifs of landslide prone slopes is introduced. The suggested approach is based on a new theory of forming of the limited equilibrium in rock massifs which includes: Coulomb-Mohr's criterion for the limited state equilibrium of rocks, the concept of the rock structural strength σstr (for compression), the interaction of active and passive pressures in slope massif. The equation for the limited state equilibrium in a ground massif in the area of force disturbance, which determines the critical situation, foregoing an appearance of destructive deformations was obtained. Theoretical regularities were confronted with the results of the field observations of concrete landslide slopes, among them the landslide in the Eastern-Maritskiy coal opencast mine (Bulgaria, 1966).
