摘要

针对深基坑支护的多支撑地下连续墙结构，考虑分步开挖和支撑对墙体的内力和位移以及支撑反力的影响，提出以弹性地基梁为基础的矩阵位移法。在求解矩阵位移法的过程中，确定土体的水平基床系数成为分析地下连续墙变形和内力的关键。Melan给出半无限大弹性空间内部线性荷载作用下的应力和位移解，在Melan解的基础上，通过对其应力解进行积分处理，并结合平面应变问题的物理方程和几何方程，得到条形荷载作用下的位移解，进而得到水平基床系数。将Melan解的矩阵位移法运用到工程实例中，并将实测结果与计算结果进行比较，验证了其可行性和正确性，可为同类工程结构设计提供理论基础。

Abstract

For multi-braced diaphragm wall structure calculation

a matrix displacement method based on the theory of elastic foundation beam is derived considering the effects of staged excavation upon internal force and displacement as well as the bracing force. Based on the Melan’s solution

combining with the geometrical plane-strain problems

a displacement solution in semi-infinite elastic under horizontal strip load is derived. Furthermore

the horizontal foundation coefficient applied to the above matrix displacement method is gained. Compared with measured results of diaphragm wall obtained from engineering cases

the analysis results indicate that the matrix displacement method is convenient and feasible

and it can provide references to the similar projects.
