We consider the problem of interaction of a reinforced concrete sheet pile wall and the ground mass, under its own weight and an external load. The process of the stressed-strained state of the system is analyzed, taking into account the creep properties of soil degradation, depending on the intensity of accumulated creep deformation and gradual excavation. Creep is taken into account based on the theory of hardening. Strength is measured by Coulomb - Mohr criterion. The imiting surface is approximated by a quadratic function. The asessment of safety of the limit load for a system of sheet pile wall and the ground mass is based on the kinematic and static theorems of limit equilibrium. As an example, the problem of estimating the bearing capacity of soil in the construction of a building is considered.
