| 摘 要： | 地铁已成为大城市中家喻户晓的重要交通工具，在地铁旁建建筑物就不可避免的会对地铁隧道造成影响。结合南京市绿地广场·紫峰大厦的基坑工程，运用3维有限元法计算模拟了基坑开挖的不同阶段，定性地分析了隧道的位移规律。与实测资料进行对比，发现有限元结果与实测资料取得了较好的一致，表明有限元方法能很好地模拟此类问题。为类似工程的设计和施工提供了计算验证。 |

| Abstract: | Subway has become an important way of transport in large cities, the subway will be inevitably effect by building near it. The different construction stages of Nanjing Greenland Square Zifeng Tower were simulated with 3 D FEM , and were qualitatively analyzed the displacement＇ s rules of the tunnel. Finally it is found that the results of 3 D FEM obtained good agreement with the measured datas. So the 3 D FEM could be a good method for simulating this kind of problem. A test calculation was provided for the design and conatruetion of a project. |
