Abstract The present paper provides numerical simulation of interaction of wave processes in the system “soil massif – underground pipeline” in explosion of charge on the surface of ground. Construction is considered in the framework of nonlinear theory of shells of Tymoshenko type. Soil is modelled by a solid porous multicomponent visco-plastic medium. The study establishes patterns of changes in stress-strain state of system depending on depth of pipeline laying and its diameter.
