| 摘 要： | 针对深基坑土钉支护工程，运用FLAC3D有限差分程序对东莞尚书银座工程基坑的土钉支护结构进行了模拟分析，研究了七种不同工况下开挖面的水平位移、坡顶竖向位移、土钉所受的拉力，实现了对施工过程的动态模拟。模拟结果与实测结果吻合较好，表明该法可用于指导深基坑支护结构工程的信息化施工。

| Abstract: | Against soil-nailed support project for deep foundation pit, such support structure for the foundation pit of Shangshuyinzuo in Dongguan is simulated and analyzed by FLAC3D finite difference program so as to study the horizontal displacement of excavation face, vertical displacement of slope top, and tensile force on soil nail under seven cases and implement the dynamic simulation on the whole construction course. The simulated results agreeing with the measured results well show that this method can be used to guide the information-based construction of support structure project for deep foundation pit. |
