某地下站点基坑工程属于典型狭长深基坑,长115.8M,标准段基坑宽23.1M,基坑开挖最深处23M,基坑采用地下连续墙围护结构加支撑系统方式。为保证基坑工程及周边环境的安全,对该基坑工程施工过程及施工之后进行监测,以提供及时准确信息反馈。本文对该基坑工程监测结果进行分析论述,结果可为类似工程作经验参考。
The underground pit excavation project belongs to a typical narrow and long deep foundation pit with a length of 115.8M. The standard section foundation pit is 23.1M wide and the deepest pit excavation is 23M. The foundation pit adopts the underground continuous wall retaining structure and the supporting system. In order to ensure the safety of foundation pit works and the surrounding environment, the construction process of the foundation pit and the monitoring after construction shall be monitored so as to provide timely and accurate information feedback. This paper analyzes and discusses the monitoring results of the foundation pit project. The results can be used as reference for similar projects.
