Abstract:
In order to analyze the mechanical characteristics of the passive pile adjacent to the surcharge load or in an unstable slope, according to the pile-soil lateral interaction mechanism, the passive pile is divided into three sections including the free section, the passive section and the active section. The distribution patterns of the additional passive load subjected to the lateral soil displacement are assumed as a quadratic function. Based on the Euler-Bernouli beam theory and the Winkler foundation model, the general calculation model of the passive pile subjected to the lateral soil displacement is derived. Then, the differential equations of each sections of the passive pile are drawn out. According to the continuity conditions on the interface of each pile section and the boundary conditions at the top and the bottom of the pile, the analytical solution of the pile response is deduced. Finally, the reliability of this analytical solution is verified by analysis of examples. And the main influence factors of the response of the passive pile are analyzed. The results show that with the increase of the passive load due to the lateral soil displacement and the decrease of the ground soil resistance, both the bend and the lateral displacement of the pile increase.
