ANALYSIS OF CHANGES IN THE STRESS-STRAIN STATE AT A POINT IN GEOENVIRONMENT

Under natural conditions, the stress-strain state of the geological environment is formed according to the Coulomb-Mohr law (for principal stresses). The lithospheric pressure (by analogy with atmospheric one) is created at each point of geological massif under the weight of overlying deposits. Stabilization of the ground state at each point of the geoenvironment is ensured by self-organization of the stress-strain state in accordance with the Mohr-Coulomb law, which links the pressure and ground strength at a given point. The stress-strain state of soils in samples was analyzed using laboratory compression tests (with determination of acting pressure and soil strength characteristics) and compared to that in natural conditions at a point of the massif. The conditions for reaching a limit state and the manifestation of destructive soil deformations at a point are considered.
