摘要
水利工程施工中,深基坑开挖是重要的施工步骤,开挖过程中容易引起地表沉降、地下连续墙和基坑坍塌等一系列风险,因此合理评估深基坑开挖项目的安全性十分重要。以某深基坑项目为例,采用最新的Plaxis 3D软件进行建模分析,对比分析了不同开挖工况下基坑渗流、地下连续墙变形以及地表沉降规律,研究成果可为相关工程提供参考。
During the construction of water conservancy projects,deep foundation pit excavation is an important construction step,but it is easy to cause a series of risks such as surface settlement,underground diaphragm wall and foundation pit collapses during the excavation process,so it is very important toreasonably evaluate the safety of deep foundation pit excavation project.Taking a deep foundation pit project as the example,the latest Plaxis 3D software was used to model and analyze the deep foundation pit project in this paper.And the laws of foundation pit seepage,underground diaphragm wall deformation and surface settlement under different excavation conditions were compared and analyzed.The research results can provide referencesforrelevantprojects.
