Behavior simulation and bearing capacity estimation of a thin-walled structure–soil system with account of soil creep and degradation

This paper proposes a method for calculating the bearing capacity of a thin-walled structure–soil system taking into account the creep and degradation of the soil strength characteristics in the process of excavation. Evaluation of the limit load is based on the kinematic and static theorems of the limit equilibrium theory. The limit state of the system is determined with consideration for the change in the stress-strain state during the gradual excavation of the pit. As an example, the problem of estimating the bearing capacity of a sheet pilling-soil system is solved.
