The physical laws control the state of matter in nature and under an anthropogenic impact. The Pascal and Mohr–Coulomb laws determine the initial stress state in air, water and geological environments within the Earth’s gravitational field, forming the pressure value in each point. Geoenvironment follows the Mohr– Coulomb law in the principal stresses under compression conditions. The thrust pressure arises when the value of the vertical stress from the weight of the overlying masses to a soil layer exceeds the structural strength of this soil (in the considered point). For an initial state of a massif occurring in quiescent mode (when the force is not applied) in the Earth’s gravitational field, its stability is maintained in all points of the geological environment. In accordance with the physical laws, a local force disturbance during the preparation of destructive deformations in the soil mass in the form of a landslide, a sinkhole over an underground cavity or soil heave from the foundation (stamp), transforms the initial stress field causing the formation of dissipative geological structures (DGS). The regularities of the formation and functioning of the DGSs are the basis for assessing the limit state in a local zone of the soil mass, as well as the features and scale of destructive deformations upon the DGS separation from the undisturbed ground massif. 

Key words: principal stresses, dissipative structures, the Mohr–Coulomb theory, ground massif
