| 摘 要： | 从工程实用角度出发，建立一个以被支挡土体假想滑裂面为分界面，滑裂面以上采用土拱理论，滑裂面以下采用土抗力法的分析计算模型，考虑深基坑空间效应及支护桩顶的水平图梁作用，对双排桩支护结构体系进行三维分析，并编制了大型程序使双排桩支护结构分析计算软件化，算例的计算对比表明该计算方法的可行性。

| Abstract: | In the light of engineering application, an analytic method on retaining structure with double row piles is proposed. The method is based on the theory of soil arching applied upward and subgrade reaction method downward regarding the divide of supposed slip surface. Three dimentional analysis is made for it considering the spatial effect of deep foundation pit and horizontal beam effect on the butt of retaining.An program is worked out based on these theories, and its feasibility is showed by the comparision of calculating results |
