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 str (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).

Keywords: slope stability, stress and strain state, limited equilibrium, landslides.
