Estimation of temperature stresses in a homogeneous isotropic rock mass under conditions of a nonstationary temperature field

When operating working at high amplitudes of the seasonal variations in air temperature and exploiting large-scale concrete construction, under conditions of temperature exchange with the surrounding rock mass, in mine aeration at great depths of the North deposit development, etc. recording of temperature influence on the stress strain state of the rock mass is required. Problems on the stress strain state of the rock mass exposed to the thermal influence are solved by method of boundary singular integral equations. To describe processes under conditions of nonstationary temperature exchange, temperature field dynamics is considered. When solving the problem in the plane statement, questions of formulating the boundary conditions are examined. Results are cited for the applied problem solution, in particular, stress strain state is studied in the vicinity of the working, located in the pit edge. The problem was solved for the ponderable half-plane. It is shown that in the specific cases, applied problem solution allows to obtain qualitative and quantitative estimation of temperature stress influence on the stress strain state of the rock mass.
