地铁结构安全保护监测方法的探究

Exploration on Monitoring Method of Subway Structure Safety Protection

针对南昌市地铁沿线基坑开挖项目对地铁主体结构、区间隧道及附属设施是否造成影响的问题,本文结合某具体基坑施工工况,对地铁保护区监测控制网的布设、监测点点位的选取、监测方法的选取等进行了详细的论述,并通过对监测数据的整理与分析来判定地铁沿线基坑开挖工程是否影响地铁结构的安全,进而判断是否会影响地铁运营的安全。

In response to the question of whether the foundation pit excavation project along the subway of Nanchang City has an impact on the main structure, tunnels and ancillary facilities in the tunnel of the subway, in this paper, combined with a specific construction conditions of the pit, the monitoring and control network, the selection of monitoting points, the selection of monitoring methods of the Protected area of Metro arc discussed in detail. And through analysis and consolidation of the monitoring data, we determined whether excavation of underground excavation along subway line will affect the safety of metro structure, and then determine whether it will affect the safety of subway operations.
