The processes of deformation of the Earth's surface are caused by the displacement of layers of soil mass lying under the surface. Shifts in the layers of the soil massi f are caused by the organization of mine workings. All this determines the regularity of the evolution of the stress-strain state of structures located in the mine construction zone. All this makes the task of studying the patterns of such behavior urgent. The influence of deformation of the soil mass on the load-bearing elements of various structures is studied. The level of deformations in the soil layer, which corresponds to the critical condition of the structure, has been determined. The data are presented on the basis of numerical solutions of boundary value problems on the interaction of the structure with the soil mass. The simulation was carried out using the ANSYS software package. The simulation results contain information about the distribution of the parameters of the stress-strain state of the structure depending on the deformation of the undermined zone. The limiting parameters of the deformation state of both the foundation array and the structure itself are determined. © 2022 The Authors. Published by ELSEVIER B.V.

Introduction and problem formulation Deformations of the earth's surface in the territories of potash deposits occur for quite a long time. These times are calculated in decades. The processes of deformation of the earth's surface are caused by the shift of the soil mass layers that lie below the surface. Shifts in the layers of the soil mass are caused by the organization of mining workings. All this determines the pattern of the evolution of the stress-strain state of structures that are located in the undermined area.
