摘要
采用比奥固结理论和修正剑桥模型，将平面有限元法应用于上海地区软土基坑围护体系的受力及变形分析。用编制的电算程序计算支撑点位置变化的各种工况，并进行深入分析，总结出支撑点位置变化对挡墙位移和桩身内力的影响规律，可为基坑支护方案设计提供参考。
The theory of Biot consolidation and modified model of Cambridge Clay are adopted in this paper,and the plane FEM is applied to the study on the force and deformation of pitbracing system in Shanghai Clay.Various engineering cases are calculated and analyazed with computing program .The law that the displacement of retaining wall and the force of piles vary with factors above is approached.This paper provides reference for the project designing of pit bracing.
