摘　　要：以污水处理厂沉淀池基坑的开挖与回填工程为例,采用非线性有限元方法借助FLAC3D软件对不良地质条件下基坑开挖与回填进行模拟分析,同时通过有限元方法模拟计算作业区内土体的应力及相应位移,根据模拟得出的应力场及位移场指导现场施工作业。Taking the project of excavation and backfilling of sedimentation basin foundation pit in sewage treatment plant as an example,using nonlinear finite element method with the help of FLAC3D software to analyze and simulate the excavation and backfill of foundation pit underthe bad geological conditions,and simulates the stress of the soil mass and corresponding displacement,then according to the simulation of stress field and displacement field guides field construction work.
