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.</p>stressanisotropyelasticitystriphalf-planeнапряжениеанизотропияупругостьполосаполуплос- кость[1.
