摘要
基于某地铁站深基坑开挖工程。本文运用有限元分析软件MIDAS GTS对基坑开挖和支护过程进行仿真模拟,通过分析基坑和高架桥在不同距离下桩基的位移变化,得出结论:高架桩基距离基坑10m以内时,基坑开挖会对桩基的稳定性造成较大影响,距离基坑20m以上时影响较小,不会对高架桥的稳定造成破坏,给施工提供理论支撑。
Based on the deep foundation pit excavation project of a Hefei subway station. In this paper, the finite element analysis software MIDAS GTS is used to simulate the excavation and supporting process of foun- dation pit. By analyzing the displacement of the pile foundation under different distances, it is concluded that when the distance is within 10m, excavation of foundation pit will have a greater impact on the stability of the pile foundation, when the distance is more than 20m, the stability of the viaduct will not be damaged. All these provide theoretical support for the construction.
