Lateral response characteristics of single pile in the inclined soil surface under lateral loads

Feng WU, Jinghai GONG, Yang ZHUO


The existing methods to evaluate the lateral bearing capacity of single pile foundation is based on the assumption that the soil surface is level. However, no mature evaluation method is available for the lateral bearing capacity of the pile in the inclined soil surface now. In this study, the lateral response characteristics of pile under lateral loads are studied via laboratory model test. Based on the effect of slope gradient study, a correction formula is proposed for the calculation of the displacements of soil surface and pile head, and the value/location of maximum bending moment along the pile length. The formula can provide a theoretical reference for single pile foundation design and calculation in the inclined soil surface.
