深基坑开挖对周边环境影响的有限元分析

FEM Analysis on Excavation Affection of Deep Foundation Engineering

结合上海地区一实际工程,采用有限元分析方法对深基坑开挖对周边环境的影响进行理论预测,分析了在已定支护方式情况下的基坑安全性问题。预测结果表明:基坑开挖对周边环境的影响均在控制范围,周边建筑物及管线均是安全的;并提出了该深度基坑地表沉降的分布规律,该预测结果可用来指导施工,也可为类似工程提供借鉴。

Based on the foundation engineering of Shanghai, The FEM method was adopted to analyze the affection to the surroundings for the excavation of deep foundation engineering, with the planned support styles. The calculated results show that the affection can meet the demand, it can be deduced that the buildings and pipelines around are both safe. And the distribution system for the settlement of the surrounding ground has also been presented. The result can be used to conduct the construe tion, and also can be used for reference for similar engineering.
