分段等值梁法在地下连续墙结构设计中的应用

Application of the Segmented Equivalent Beam Method in the Design of Underground Continuous Wall Structure

近年来采用结构力学力矩分配法计算连续梁的等值梁法应用很多,但是该方法未考虑到深基坑逐层开挖施工的影响,而分段等值梁法恰好考虑到土方开挖和支撑设置顺序的影响。对某地铁车站地下连续墙设计采用此方法进行计算,可为今后类似工程的设计提供一种更为合理的内力计算方法。

In recent years, the application of equivalent beam method for using moment distribution method of structural mechanics to calculate continuous beams is very common, but this method does not take into account the impact of the construction of deep foundation pit excavation layer by layer, and the segmented equivalent beam method exactly considers the effect of earth excavation and supporting setting order. Applying this method in the design of underground continuous wall structure of a subway station can provide a more rational calculation method for the future design of similar projects.
