摘要
模拟基坑开挖周边土体应力状态,在真三轴仪上进行了相关应力路径试验,摸索土体变形特征;针对其变形特性,采用有限元程序,对土体变形进行了数值模拟,其结果较接近实际。
By simulation the soil＇s stress state around the foundation during excavation,the related stress path tests has been carried out on the true triaxial apparatus,in which the soil＇s deformation characteristics is studied.According to its characteristics,the soil＇s deformation is simulated by FEM and results are approached to the engineering.
