杭州某基坑施工地铁保护监测方案研究

Research on Protection and Monitoring Scheme for Subway in Construction of Foundation Pit in Hangzhou

随着轨道交通的与日俱新,越来越多的地下项目尤其是基坑项目无可避免地会靠近既有或新建地铁区域。这就对有关地铁保护的监测提出了更高的挑战。现以杭州地区某基坑为例,重点介绍该项目施工期间,对地铁保护区范围内的隧道、车站等进行监测设计,以通过严密的监测,自动监测与人工复测表明方案的可靠,为地铁的安全运营提供了保障。

With the development of rail transit,more and more underground projects,especially the foundation pit projects,will inevitably be close to the existing or new subway areas,which poses a higher challenge to the monitoring of subway protection.Taking a foundation pit in Hangzhou as an example,the monitoring design of the tunnels and stations within the subway protection areas in this project construction is specially introduced.The reliability of the scheme is demonstrated through strict monitoring,automatic monitoring and manual retest,which provides the guarantee for the safe operation of the subway.
