Calculation of the foundations in compacted excavations with extended base, applying boundary elements method

Abstract

Numerical realization according the boundary element method (BEM), intended for the determination of the pressed piles strength with the expanded basis on the base of the provisions of the dispersive soil mechanics is carried out. In the given research the mathematical tool is supplemented with the experimental laws of shearing soil deformation - general regularities of the soil volume change in case of shearing (dilatance and contraction) involving V.M.Nikolaevskyi, I.P.Boiko dilatancy relations are taken into account.
