邻近地铁超大圆形支撑深基坑施工技术

Construction Technology of Super Large Ring Support for Deep Foundation Pit Adjacent to Subway

上海阳明花园广场二期二阶段深基坑工程紧邻地铁,周边环境相当复杂,施工难度大。针对工程难特点,介绍了圆环支撑围护、土方盆式开挖、钢支撑应用、信息化监测等施工技术。经实践,取得了预期的效果,可为类似项目提供参考。

The deep foundation pit project of second stage of Shanghai Yangming Garden Plaza Phase II is adjacent to the subway.The surrounding environment is quite complex and the construction is difficult.According to the difficult characteristics of the project,the construction technologies such as foundation pit ring support,earth basintype excavation,steel support application and information-based monitoring are introduced.Through the practice,the expected effect has been achieved,which can provide reference for similar projects.
