上海虹桥商务区02-B地块深基坑支护设计

软土地区的深大基坑支护设计应综合考虑开挖面积、开挖深度、周边环境及地质条件等因素,文中介绍了上海虹桥商务区02-B地块深基坑支护设计方案,设计重点考虑了与相邻地块的开发进度关系及对南侧管沟的保护,并采用有限元对变形进行了数值分析,最终监测数据表明,本工程采用的支护措施可以有效控制基坑变形,未对周边道路及管沟造成不良影响。

THE EXCAVATION DESIGN OF AREA 02-B OF HONGQIAO BUSINESS DISTRICT IN SHANGHAI

In the soft soil area,deep foundation pit support design should take into account the excavation area,excavation depth surrounding environment and geological conditions.In this paper,the excavation design of area 02-B in Hongqiao business district of Shanghai was taken as an example to show the influence of the development progress on the design and the protection measures for the pipeline in the south of excavation.The finite element method was used to carryout the numerical analysis of deformation.The motoring data shows that the supporting measures adopted in this project can effectively control the deformation of the foundation pit and do not adversely affect the surrounding roads and trenches.
