浅议明挖地铁车站深基坑施工技术应用

Discussion on the Application of Construction Technology of Deep Foundation Pit in Open-cut Subway Station

地铁车站主体结构是否能够顺利实施,涉及深基坑作业。深基坑是系统工程,指开挖深度超过5m(含5m)的基坑的土方开挖、支护、降水工程;具有综合性强、区域性强、个性强、时空与环境效应及支护体系临时性特点,施工时必须监测。

Whether the main structure of the subway station can be implemented smoothly involves deep foundation pit operations.Deep foundation pit is a systematic project,which refers to excavation,support and precipitation engineering of foundation pits with excavation depth exceeding 5m (including 5m);it has strong comprehensive and regional characteristics,strong personality,space-time and environmental effects and temporary support.It must be monitored during construction.
