上海临港地区紧邻地铁车站深基坑工程施工技术研究

Study on Construction Technology of Deep Foundation Pit Adjacent to Subway Station in Shanghai Lingang Area

以上海临港新城滴水湖站交通枢纽工程为例,对上海临港地区紧邻地铁车站超大型深基坑工程的施工过程控制技术进行研究。以基坑围护监测数据为主要依据,对基坑施工期间紧邻地铁车站结构有效保护和局部基坑发生应急处置的原因进行对比分析,并对上海临港地区不良地质条件下的深基坑工程围护结构设计和施工控制措施提出建议,为类似基坑工程提供参考。

Taking the transportation hub project of Dishuihu Station in Shanghai Lingang New Town as an example,the construction process control technology of super large deep foundation pit project adjacent to subway station in Shanghai Lingang Area is studied.Based on the monitoring data of foundation pit support,the causes of effective protection of structures adjacent to subway stations and emergency treatment of local foundation pits during foundation pit construction are compared and analyzed,and some suggestions on the design and construction control measures of retaining structure of deep foundation pit engineering under adverse geological conditions in Shanghai Lingang Area are proposed.It provides a reference for similar foundation pit engineering.
