| 摘 要： | 根据武汉地铁2号线江汉路站的地质条件,给出了基坑围护结构的两种设计方案：地下连续墙-排桩组合方案和全地下连续墙支护方案,通过有限元模拟了两种围护方案下基坑开挖过程中围护结构的响应,结果表明：排桩-地下连续墙围护结构变形严重不对称,地下连续墙变形较大;全地下连续墙围护结构变形合理,变形值满足规范要求,从而确定全地下连续墙为最终支护方案,为类似工程设计提供参考。

| Abstract: | Based on the geological conditions of Jianghan Road Station of Wuhan metro line No.2,there are two possible supporting schemes for deep foundation pits,the combination of row piles with diaphragm wall and the diaphragm wall only.In order to select the best supporting scheme for the foundation pit,the two schemes are compared and analyzed by the finite element method.The conclusion shows if the combination scheme is used,the deformation of the enclosure structure is unsymmetrical seriously,and the deformatio... |
