摘要
Abstract
This paper takes Chengdu Universiade sewage treatment plant as the research object and intro-duces the geological conditions,support form and construction process of the project.Finite element nu-merical simulation is used to simulate the deformation characteristics of the foundation pit under different excavation conditions,and the calculation results are analyzed in comparison with the results monitored.The results show that in pit excavation,there is an obvious positive correlation between the settlement de-formation of the soil around the pit and the depth of pit excavation.The settlement deformation and hori-zontal displacement of the soil around the pit show that the deformation in the direction of the long side is larger than that in the direction of the short side,and the position at which the largest deformation occurs is at the middle of the long side.The horizontal displacement of the soil on the top of the pit has the lar-gest deformation in pit excavation and support,which should be controlled within the safety value in con-struction.关键词
