The article analyzes the effect of deformation anisotropy on the stress‐strain state of the soil basement on the basis of a numerical experiment using the ANSYS software package. Strain properties of environment are determined by strain module E and Poisson's ratio μ. Resulting from calculation experiments, transverse‐isotropic environments were concerned with coefficients of stress‐strain anisotropy k a =0.5; 0.75; 1.33 and 2 and additional coefficients a a (α') are obtained, which are used in determining vertical stresses from the additional load. Based of obtained results a method is proposed for calculating the additional stresses of the anisotropic basement of the foundations of the existing building from the buildings and structures being erected. The calculation is based on the Lyave problem using the scheme of a linearly deformed medium. The anisotropic properties are taken into account by introducing an additional coefficient α', which depends on the degree of anisotropy of the soil basement k a and the geometric dimensions of the foundation.
