The results of calculations based on the equations of the plane problem of the theory of elasticity for determining stresses in a three-layer anisotropic base under the action of a static normal surface load are presented. It is considered a variant of the complete cohesion between the layers. The stress functions in each layer are written through the normal and tangential forces arising on the line of contact between the strip and the half-plane. The contact forces between the strip and the half-plane are determined from the system of two equations and conditions on the surface of the base. As a result, the stress functions in each layer are written through the surface load in the form of improper integrals. An analysis of the stress state is carried out according to the model of a three-layer iso- tropic base, depending on the elastic characteristics of the material of the layers. The influence of anisotropy of the material of layers in a three-layer soil mass is shown.
