Abstract. A method and an algorithm are designed to determine self-stress parameters for hardening grouting mortar. The method can be considered as an equivalent to a spatial problem of rigid punch pressing into cylindrical body end of finite size. Boundary conditions of the problem are formulated. Analytical relations between components of the stress tensor are defined which describe the grouting rock self-stress depending on the rock physical and mechanical properties. A method was created to solve equilibrium equations for elastodeformed bodies in cylindrical coordinate system. Various calculations are presented, which indicate that the designed method allows to define grouting rock self-stress in a concrete area except for specific points which are located in close proximity and require special solutions for the rigidity.

Keywords: method, algorithm, plugging solution, self-stress, the equilibrium equations of elastic-deformable body in a cylindrical coordinate system.
