摘要
本文以弹性地基梁法为基础,考虑开挖过程及回筑过程对深基坑挡土结构作用的影响,建立了围护结构的内力和变形的变化过程的完整模拟。通过大量的计算结果与实测值的对比分析,讨论了该法作为基坑围护结构设计方法的合理可行性问题。
This paper presents an approach of using finite element method for simulating the behavior of flexibe retaining structure of deep excavation pit during the whole process of excavation and refilling based on the theory of beams on elastic foundation.The rationality and feasibility of the approach have been verified and discussed by comparisons of the calculated deformations of the structure to those of the observed results of a number of deep excavation pits in Shanghai.
