Comparative Study on Force Characteristics of Vertical and Inclined Cantilever Retaining Pile

摘要

In order to comparative study the force characteristics of vertical and inclined cantilever retaining pile in foundation pit engineering, a practical excavation engineering was considered. Based on the engineering geological conditions of this foundation pit, two three-dimensional simulation models for computing the force characteristics of vertical and inclined cantilever retaining pile were built. Then the horizontal displacement of pile top, the lateral displacement and the bending moment of pile body were illustrated and contrasted in detail. It was shown that the horizontal displacement of inclined pile top is significantly less than that of vertical retaining pile. Moreover, the deformation and bending moment of inclined pile body are more reasonable than that of vertical retaining pile. Therefore, the stability of foundation pit was guaranteed through inclined pile support.
