摘要
利用Plaxis有限元软件,对上海市某超深基坑逆作法施工进行模拟计算,分别分析了地下连续墙插入比、灌注桩数量、临时支撑等对基坑变形的影响。将计算结果的变形规律进行分析,得到超深基坑的一般变形规律和变形控制要点。结论可用于超深基坑的变形预测和设计优化。
Plaxis（FEM） software was used to simulate a ultra- deep excavation constructed by top - down method in Shanghai. The paper analyzed the influence of insertion ratio of underground diaphragm wall, number of pile and temporary support on deformation respectively. It analyzed the general deforma- tion law of calculation result, and got the general deformation law of ultra - deep excavation and the con- trol points of deformation. The conclusions can be used for the deformation prediction and design optimi- zation of ultra - deep excavation.
