软土地层深长基坑变形原因分析与控制技术

On analysis of reasons for deformation at deep and long foundation pits in soft soil stradum

结合苏州地铁2号线延伸线尹中路站工程,对软土地层深基坑变形的原因进行了分析,并提出了相应的控制措施,有效控制了基坑变形及地表沉降,消除了施工风险,为在此类软土环境中的基坑施工提供了宝贵的经验。

Combining with the project at Yinzhong station along the extension line of No. 2 subway in Suzhou, the paper analyzes the reasons for the deformation at the deep foundation pits of the soft soil stradum, and points out respective controlling measures, so as to control the foundation pit deformation and ground settlement, eliminate construction risks, provide experience for the foundation pit construction in the soft soil environment.
