Analysis of Pile-anchor Supporting Structure Internal Force and Building Settlement around Foundation Pit

Changzhi Zhu, Shijie Wang

Abstract


The method of field test combined with numerical analysis can effectively ensure the stability of deep foundation pit engineering, in this paper, taking the pile-anchor supporting structure as an example, we put forward the analysis scheme, which is the monitoring of pile internal force and deformation combined with numerical analysis. The results show that: First, the stress and deformation of foundation pit supporting system has obvious space effect. Second, the numerical analysis method can be used to analyze the deformation law of supporting system, and offer effective guidance for design and construction of foundation pit excavation and support.

Keywords
