夹心桩基坑支护大变形分析

Large Deformity Analytic of Shoring Structure with FillingPile Construction Method

针对可回收的夹心桩支护结构 ,基于T L坐标建立了初始构形的大变形增量有限元方程 .引入自修正迭代算法 ,用编制的FLSAC大变形程序 ,对夹心桩支护结构的受力和变形特征进行了分析 .为支护结构设计和选取支护结构参数提供了依据 .

To the reclaimable filling pile shoring structure,establishes the increment finite element equation of original formation on the T L coordinate The big deformity program(FLSAC) is authorized with introducing self-modify iterative arithmetic They are analyzed that the deformity and passive pressure characteristic of shoring structure with filling pile The designing parameters of shoring structure are afforded
