The results of the finite element analysis of stress distribution in the soil two-layer strip foundation, depending on the type of design scheme are presented. It was placed that on the distribution of stress character influences the ratio of the deformation modulus of contact layers and the power of the latter. It is shown that on the contact layers under the condition of their full adherence to the contact there is a “jump” of the numerical values of all three components of the stress, which decays as moving distance from the contact. For some thickness values of the upper layer, the ratio of their deformation module ceases to have effect on the distribution of stresses. This value thickness depends on the intensity of the external load and its width. Accounting of the foundation’s depth to any of the three reviewed in the article methods greatly reduces the stress level in comparison with the calculation results in the case when the design scheme is accepted in the form of a half-plane, which is attached to the surface of a uniformly distributed load.
