圆形地下连续墙的弹性地基梁数值计算法

本文基于圆形地下连续墙起拱效应以及沿墙高变刚度的实际情况,提出了圆形地下连续墙弹性地基梁分段数值计算模型。与有限元法相比,在计算精度相同的情况下,使用该法易于编写电算程序和上机计算。本文还给出了采用该法时一些基本参数的确定方法。

THE NUMERICAL SOLUTION OF THE ELASTIC FOUNDATION BEAM ABOUT CIRCULAR UNDERGROUND CONTINUOUS WALL

Based on the arch action of circular underground continuous wall and the fact of variable stiffness along wall height, this paper developedthe numerical solution model of the elastic foundation beam about circularunderground continuous wall. The computing program of this model can be writtenand used much more easily than that of finite-element method under the same precision. This paper also gave the method to determine some basic Parameters of this model.
