Geotechnics of the calculation study of the bearing capacity and deformation of granular soil of the base of a cast-in-place pile in a punched well

The results are presented of an on-site field experiment within the research of the bearing capacity and settlement deformation of granular soil of the base of a cast-in-place pile in a soil-displaced punched well. The methodology of a calculation study is developed, and the theory and methods of calculating the tension of five zones of limit state of soil elastic equilibrium in the base along the side surface of the circular cone and shaft of the considered pile are described. The substantiation is given for the choice of the zones of limit state of soil elastic equilibrium involved in the experiment with the cast-in-place pile in the base. The calculation of the ultimate bearing capacity of soil of the base and of the cast-in-place pile settlement in the punched well is presented, and the calculated graph of the pile settlement dependency on the load is built. The results of the research are summarized in the conclusion.
