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.
