On the basis of the received by the author’s solution of the main mixed problem of the flat theory of elasticity the issue of distribution of tension in homogeneous and isotropic stamping sheet located under the impact of vertical evenly distributed load of constant rate at various friction coefficient values on the “tool – soil”. It is shown that at any friction coefficient values on “tool - soil” contact stress field under the tool is symmetrical towards vertical axis passing through its middle. It predetermines the fact that when reaching value load of limit values of the bearing capacity only symmetrical bilateral bottom heave from below the foundation can occur and it corresponds to design models by L. Prandtl and R. Hill used in geomechanics. The authors consider the compliance of classical solutions of problems of tool with the obtained results and the mentioned design models.
