| 摘 要： | 利用FLAC3D,模拟设计要求和最不利状态情况下某地铁车站深基坑工程开挖。研究得出土岩基坑的变形规律特点,模拟结果同时表明:基坑周边的荷载对土体沉降影响较大,对支护桩侧向位移影响较小,且车辆荷载比堆载影响大;有无支撑对基坑变形影响较大。

| Abstract: | Simulated two cases of excavation for deep foundation pit in a subway station using FLAC3D: the design requirements and the most adverse conditions.Research unearthed rock excavation deformation regular features,the simulation results also showed that: the load of around foundation soil subsidence greater impact on smaller lateral displacement of the supporting piles,and vehicle load heap load impact;no support larger pit deformation. |

| Keywords: | foundation pits in rock-soil supporting piles rules about deformation numerical simulation |
