| Abstract: | This paper studies, by means of finite element program ANSYS, the three-dimensional finite element numerical simulation of single pile in pile-soil interaction system. In static loads, the significant effect of the nonlinear soil behavior, the pile-soil interface separation, and the pile slenderness and width on the response of a single pile are analyzed. Through comparing Trochanis numerical results,the present results of this work truly reflect the response of single pile in static load,and indicate all kinds of nonlinear factors act on the pile-soil interaction system. |
