Abstract. The purpose of the study was to consider the possibility an adequate definition of the stress-deformed state (SDS) of grounds of basis at the appearance of a pressure source. The current approach is based on the fundamental decisions and the principle of superposition. However, there is no solution to the problem of determining the SDS of grounds of basis, taking into account their place in phase transitions, such as the freezing of pore fluid.
This paper presents an exact analytical solution of the fundamental problem concerning the SDS of the elastic half-space, which includes a point source of pressure inside. The resulting fundamental solution will expand the class of problems of definition of SDS of grounds of basis and rock mass tasks, which cause stresses and deformed are occurring in these physical processes caused by phase transitions. These include the problem of determining the SDS of grounds of basis and the rock mass area around the workings in the ground frost heave, high-pressure injection, artificial freezing of ground, heaving rocks, evaluation of the stress-deformed state of the matrix in the process of crystal growth of the solid phase, etc.
Keywords: grounds of basis, rock mass, stress-deformed state, the phase transition.
