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 to reasonably 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 references for relevant projects.
