桩锚支护体系在基坑工程中数值模拟

Numerical simulation analysis of pile-anchor support system in deep foundation pit

通过对一个基坑支护设计实例进行数值模拟,基于对基坑桩锚支护设计土压力计算理论详细介绍,并利用ABAQUS有限元软件对基坑和桩的变形进行了详细的分析。结果表明,桩锚支护体系在基坑支护中,排桩和桩后土体变形呈"中间大,两头小"的变形趋势。

The work presented in this paper focuses on several aspects of the follows. Through the numerical simulation of a foundation pit project with an example of pit supporting design,this paper researches the theoretical calculation and the stability analysis of the foundation pit,based on the detailed introduction to the theory of the pit pile-anchor support design and calculation of earth pressure. The paper gives a detailed analysis of the deformation of the pit and pile,by using ABAQUS finite element software to simulate. The results show that the deformation trend of soil deformation in pile and pile is"large in the middle and small in two ends"in foundation pit support.
