| 摘 要： | 地下连续墙是上海地区深基坑的主要围护形式.根据上海软土地区50个深基坑工程的实测结果,研究了连续墙的变形特性,包括基坑开挖深度、支撑系统的相对刚度对连续墙最大侧移的影响,最大侧移的深度及墙后软土层厚度对基坑变形特性的影响,得到的若干规律性结果,可为今后同类基坑工程的设计提供参考.

| Abstract: | Diaphragm wall is widely used as soil retaining structure in deep excavation in Shanghai. Based on 50 case histories of deep excavation supported by diaphragm wall in Shanghai soft deposit, the deformation properties of diaphragm wall are studied. The study includes the relationship between the excavated depth as well as the relative stiffness of the supporting system and the maximum lateral displacement of the diaphragm wall, the location of the maximum lateral displacement, and the influence of the thickness of the soft soil behind the wall on the deformation properties. Some conclusions drawn from this analysis can provide useful reference for the design of deep excavation in soft soil. |
