Abstract
Since reliability of foundations depends on the ability to assess engineering and geological conditions of bases, their hydrogeological situation, change in these properties during construction and operation, there is a need to attract latest advances in soil mechanics, modern numerical methods and computers to calculate reliability of the bases. A wide dispersion of engineering-geological conditions, a variety of building structures excludes standard approach to the design of bases and foundations and requires creative reflection. Ring foundations (like chimneys, cooling towers, silos towers, radar stations, towers) are the most suitable and economically advantageous for round in plan constructions. They are less material-intensive and reduce the cost.These factors are important for an investor. The distribution of pressure in the soil base of the ring foundations has quantitative and qualitative differences from foundation structures of another form (round, rectangular, belt), which requires their reliable calculation. In the article, the ring pile foundation of the silos is optimized by the method of boundary elements. The technique for calculating bearing capacity of a ring grill and an annular pile field is presented. To compare the work of piles in a bush and a single pile using the BEM, a nonlinear problem of the behavior of a single pile under load is predicted.
