| 摘 要： | 以北京三峡大厦深基坑开挖支护为工程背景展开研究，运用FLAC^3D对三峡大厦深基坑的开挖支护过程进行了动态数值模拟，同时，随着基坑开挖支护的进行，实时监测基坑的变形情况，直到基坑开挖支护完成。通过数值模拟结果与实测基坑变形数据分析比较，可知数值模拟的方法应用于基坑开挖支护过程是比较可靠的，且钢管桩复合土钉墙能很好地满足基坑支护稳定性的要求。

| Abstract: | On the basis of Beijing Three Gorges Building, this paper uses FLAC3D software to carry out dynamic numerical simulation of the excavation and supporting courses of deep foundation pit in Beijing Three Gorges Building project. Meanwhile, during excavation and supporting of foundation pit, deformation of the foundation pit is monitored in real time till the completion of excavation and supporting of the foundation pit. Through analysis and comparison between numerical simulation results and measured deformation of foundation pit, it is indicated that application of numerical simulation method during excavation and supporting of foundation pit is comparatively reliable and that steel pipe pile compound soil-nailing wall can satisfy the requirements of stability of support in foundation pit. |
