根据 WEGAGEN银行大楼的地质资料以及监测数据，通过有限元软件 Midas 对该项目建立三维深基坑模型，进行数值模拟分析。介绍了有关工程情况及模型相关设置，提取支护结构变形值与实际监测变形值进行对比，说明该深基坑无水平支撑设计的可行性，并且探讨了基坑开挖过程中边坡的水平位移、竖直位移随施工工序的变化规律。

Based on the WEGAGEN BANK foundation survey and design institute,model of triaxiality deep founda-tion was established by using large finite element software of MIDAS and it was used to numerical simulation.Then this paper introduced the engineering condition and model correlation,compared the deformation-value of city structure and the observe value to verified the viability of this model.The change regulation of horizontal and vertical displace-ment while excavation the foundation pit and the influence of upper load to foundation pit were discussed.
