地下连续墙的静力计算,是迄今尚未完满解决的一项课题,正在引起国内外工程界的重视。本文拟对这一问题作一些初步探讨。作为挡土为主的地下连续墙结构,与一般板桩墙相比,既有共同之处,也有一些不同特点,例如: 1.由于地下连续墙刚度较大,变形较小,尤其在设有多层支撑或锚杆的情况下,其墙后的土压力分布往往更接近于静止土压力。 2.地下连续墙作为永久性整体结构一部分,其平面形状有时较复杂,纵向截面也可
The static calculation of underground diaphragm walls is a subject that has not yet been satisfactorily solved. It is attracting the attention of the engineering community at home and abroad. This article intends to make some preliminary discussions on this issue. As a retaining wall-based underground continuous wall structure, compared with the general sheet pile wall, there are both common and some different features, such as: 1. Due to the large rigidity of the underground continuous wall, the deformation is small, especially in the In the case of multi-layer supports or anchors, the earth pressure distribution behind the wall tends to be closer to the earth pressure at rest. 2. As a part of the permanent integral structure, the diaphragm wall is sometimes more complex and its longitudinal section can also be
