摘要
首次采用空间８节点非协调等参元方法，研究地下连续墙深基坑开挖过程中土体沉降沿基坑纵向的分布规律，并与上海地铁一号线徐家汇地铁车站的实测结果进行比较；引进了沉降传递系数的概念，据此可根据地表沉降值估算地下管线变形值，以保护沿基坑纵向的地下管线安全．所得结论可供工程技术人员参考．
In this paper, a 3D 8-noded non-conforming isoparametric FEM is first used to analyse longitudinal distribution rules for soil settlement during diaphragm wall deep excavation. The results are compared to the in-situ testing results from Xu Jia-hut Subway Station in Shanghai Subway No. 1 Lines, proving the theory is reasonable. The coefficient of settlement transmission To is introduced. The To formulation is obtained. Based on To idea, the settlement of underground pipe lines may be calculated from the surface settlement, thus the underground pipe lines can be protected. The conclusions may be refered by engineers.
