逆作法深基坑围护及邻近在建地铁变形的监测技术

Monitoring Technique for Deep Foundation Excavation Enclosure Reverse with Construction Method and Neighboring On-construction Subway Deformation

临近地铁及周边地下管线的工程施工,对基坑稳定和周边环境保护要求较高。以新苏吴地中心工程实际为例,介绍深基坑围护及邻近在建地铁变形的监测技术以及控制要点,分析了监测过程中的难点及应采取的相应技术措施。

The deep foundation excavation construction has higher requirements for foundation excavation stability and surroundings environment protection,which neighboring the subway and underground pipe project. Based on the actual project,the monitoring technique for deep foundation excavation enclosure with reverse construction method and neighboring on-construction subway deformation is introduced,and the key points in monitoring process and the corresponding measures are analyzed.
