Stresses in points of the massif are determined and distributed according to the Coulomb-More law in the main stresses, under the conditions of compression. Influence of slope and development of slope processes causes in massif, according to dissipation processes, decrease of stresses in points. The results of experimental studies (laboratory, bench and in-situ) indicate that the regular processes of stress reduction in the points of the massif cause deformation of soils already at a pre-limit stage (for the massif). But they can cause the formation of cracks in the bearing structures of buildings and the appearance of dangerous unequal subsidence of their foundations.

Key words: coulomb-more law, stress-strain state, dissipation, lateral expansion, stress reduction, laboratory, bench and field tests, slope processes, massif subsidence
