现代测绘技术在地铁隧道变形监测中的应用研究

Research and Application of Modern Geomatics Technology in the Deformation Monitoring of Metro Tunnel

通过应用对比分析,并以沈阳地铁9号线某施工段、天津地铁3号线和平路运营段隧道变形监测工作为例,介绍了GeoMos全站仪自动化监测系统及三维激光扫描技术在现代化隧道变形监测中的应用,并在测量平差理论的基础上,对实测数据进行了精度分析.结果表明,现代化变形监测技术较比传统变形监测方法在精度、效率以及自动化水平上有了明显的提高,是当今地铁隧道施工及运营维护中可靠的地保监测手段.

This research introduced the application of total station automatic Geomatic Monitoring System（GeoMos）and three-dimensional laser scanning technology.Using the actual project one construction section of Shenyang metro line9,Heping Rd.section of Tianjin metro line3,we collected the actual data from the certain projects,then evaluate the precision of these data on the basis of surveying adjustment theory and performed theoretical and comparative analysis of this in deformation monitoring project.It can prove that the modern monitoring technologies in the deformation monitoring of metro tunnel experienced an significantly development in data precision,work efficiency and automation level compared to traditional monitoring methods.These modern ways are dependable monitoring methods in the process of metro tunnel construction and urban metro protection monitoring.
