深基坑地下车站工程基坑变形控制

Foundation pit deformation control of deep-foundation pit underground station engineering

针对地下车站工程深基坑开挖阶段围护结构、中间立柱等结构变形监测情况进行了简要分析,详细介绍了在明挖、盖挖两种常规施工方法下深基坑开挖阶段结构变形控制要点和方法,为今后类似工程施工提供借鉴。

The paper analyzes the structural deformation monitoring conditions of enclosure structure and intermediate column in underground station engineering at deep foundation pit excavation phase,and specifically introduces the structural deformation controlling points and methods at deep foundation pit excavation phase by using opening-excavation and covering-excavation method,which has provided reference for similar engineering construction in future.
