Defining stress state of the pile in homogeneous foundation with the bottom places on the weak foundation

Abstract

    There are many Diesel hammers, which were used driven pile in working. Diesel hammer has piston knock the pile, so Diesel hammer presume that is an elastic bar in calculation. In this article, authors defined stress state of the pile, that was driven in homogeneous foundation with the bottom places on the weak foundation. Authors calculate impact of elastic mattress, frictional force of the side face of the pile on max compressed stress in the socking- time.
