摘要
结合具体工程施工监测方案,对受紧邻基坑施工扰动影响的运营中地铁隧道变形的动态监测方法进行了分析,通过采用基于TCA2003全站仪的全自动动态监测系统,可以24h无人值守连续监测运营中的地铁隧道变形,且每次监测可在地铁运行间隔内迅速完成。监测方法及数据采集可以实时提供给施工方以指导当前及下一步的施工方案,在工程应用中收到了良好的效果。
In combination with the construction monitoring option of the concrete project the paper analyzes the dynamic monitoring method of deformation of metro and tunnel in the operation influenced by the construction of adjacent foundation pit. To adopt automatic dynamic monitoring system of TCA 2003 full station meter can continuously monitor the deformation in operation of metro and tunnel in 24 h without person on duty. And every monitoring can be rapidly completed in the interval of the metro operation. The monitoring method and data collection can be real-time provided to the construction party for guiding the present and next step construction option. It obtains a fine effect in the application of project.
