| 摘 要： | 结合新疆中天大楼深大基坑支护工程，采用三维有限差分程序FLAC3D对坑壁土钉支护及基坑的开挖过程进行了模拟分析，并通过与现场实测数据的对比研究，研究了土钉支护技术的应用效果。结果表明，数值模拟可以实现施工全过程的动态开挖，坑壁水平位移峰值点约在基坑深度的3/4位置，土钉在基坑开挖过程中均承受拉应力。

| Abstract: | Combined with deep foundation pit support engineering of Xinjiang Zhongtian Building,pit wall soil nailing and foundation pit excavation are analyzed numerically using three-dimensional finite difference procedure FLAC3D.Through comparison with the site measured data,the application effect of soil nailing technology is studied.The result shows that numerical simulation can achieve dynamic excavation during the whole construction process,the peak of pit wall horizontal displacement is about at 3/4 of pit dep... |
