Results of pile deposits calculation analysis in difficult geological conditions with taking into account of soil nonlinear behavior are resulted. Calculation of the soil intense-deformed condition in common with the pile basis under springboards of a multipurpose sports complex is shown. Possibility of the decision of the given problem on the basis of the same technologies is shown, as at modeling of work of a separate pile. Importance of the account of mutual influence of two springboards against each other, nonlinear behavior of soils, and also ground waters is shown. Interaction of designs of springboards and a soil file under them is considered.
