摘要
在位移要求严格控制的深基坑设计中,一般采用地下连续墙作为围护结构。以上海近邻地铁一号线的摩尔大厦基坑为例,分析基坑开挖的施工措施和地下连续墙的变形特征。实践证明,沿着连续墙对基坑内外进行土体加固和盆边留土抽条限时开挖措施,对于减小地铁隧道的变形是非常有效的。
Diaphragm wall was adapted to as exterior-protected construction in tion pit when the displacement was controlled strictly. Construction measurement the design of deep foundaand the deformation of diaphragm wall were discussed based on the Mo＇er foundation pit close to metro line No.1. The results showed that foundation consolidation between the inside and outside of the foundation pit and construction in ＂layered, partitioned, time-limited excavation＂ were beneficial to the safety of metro tunnel.
