摘　　要：城市轨道交通隧道的养护是确保地铁系统安全、可靠运行的重要环节。在运营过程中,城市轨道交通隧道可能会出现各种病害,因此定期检测和维修结构病害、及时消除安全隐患,对地铁隧道运营至关重要。使用三维激光扫描技术检测运营期的地铁隧道病害,能够提高工作效率和检测结果的准确度,同时通过与分析软件结合,可以快速得到结构病害的分布和数量情况。通过与现场病害人工检测的对比分析,该方法完全能够承担检测工作,为三维激光扫描技术在隧道检测中的应用提供了指导。The maintenance of urban rail transit tunnels is an important link to ensure the safe and reliable operation of the subway system.During the operation process,various diseases may occur in urban rail transit tunnels.Therefore,it is very important for the operation of subway tunnels to carry out regular inspection and maintenance of structural diseases and eliminate potential safety hazards in a timely manner.The use of 3D laser scanning technology to detect the diseases of subway tunnels during the operation period can improve the work efficiency and the accuracy of the detection results.At the same time,by combining with the analysis software,the distribution and quantity of structural diseases can be quickly obtained.Through the comparative analysis with the on-site manual detection of diseases,this method can fully undertake the detection work and provide guidance for the application of 3D laser scanning technology in tunnel detection.
