摘要
提出基坑开挖的支护方案,采用大型岩土有限元分析软件PLAXIS3D建立整体三维有限元模型,模拟了支护方案对临近地铁线的影响,建立的三维模型以及采用的分析方法对于预测基坑开挖对周边环境的影响有比较好的效果,并对项目的实施提出了一些指导性建议,可供同类工程参考。
Supporting scheme was put forward, and three-dimensional finite element model was built by using software PLAXIS3 D to simulate the influence of foundation pit excavation on nearby subway. The model and the analysis method can be effectively forecast the influence of excavation on surrounding environment. Some suggestions are put forward for the implementation of the project, which can be referenced by the same engineering.
