【摘要】 以绍兴好望大厦半逆作法工程为工程背景,考虑软土本构关系与结构空间效应,采用有限元软件PLAXIS和ANSYS评估开挖过程中支护体系动态响应、基坑安全性以及环境影响,有效地解决了半逆作法基坑的支护结构、支撑系统及变形预测等设计关键技术问题。监测数据表明基坑安全可靠,取得了较好的经济社会效益。更多还原

【Abstract】 Considering soft soil properties and 3D structural effects,semi-reverse foundation excavation of Haowang Building in Shaoxing is analyzed by finite element analysis software PLAXIS and ANSYS.Then the dynamical response of foundation excavation supports is calculated,and safe behaviors and environmental effects are obtained.Thus some key design problems as retaining system optimization and deformation predictions can also be effectively solved.Monitoring results show that the foundation excavation is safe and reliable,meanwhile good economical and social benefits are gained.更多还原
