基于TLS技术的城市地铁工程测量研究

Study on Urban Subway Engineering Survey Based on TLS Technology

针对城市地铁工程测量中传统方法可能存在精度限制、操作烦琐以及难以获取全面准确的地形数据等问题,提出了一种新的基于三维激光扫描技术的测量方法。北京市某地铁站实地测量研究结果表明:三维激光扫描技术不仅可以获取地铁隧道内的数据,还能够准确地检查出哪些隧道位置形变较大,风险较高,研究结果可应用于城市地铁系统的规划和决策。

In view of the problems that the traditional methods in urban subway engineering survey may have precision limitation,complicated operation and difficult to obtain comprehensive and accurate topographic data,a new survey method based on three-dimensional laser scanning technology is proposed.Based on the field measurement of a subway station in Beijing,the research results show that 3D laser scanning technology can not only obtain the data in subway tunnels,but also accurately check which tunnels have large deformation and high risk.
