摘　　要：地铁隧道结构安全直接影响城市轨道交通安全,需要定期对轨道交通结构进行检测.采用移动激光扫描技术对轨道交通结构进行检测的方法,具有作业效率高、测量精度高、成果丰富及范围全覆盖等优势,通过实际项目实践应用证明,获取隧道环片的水平直径、接缝张开量、病害检测及三维变形等成果可以作为隧道结构历史档案,为服役性能评估提供翔实的基础资料,具备广泛的推广应用前景.The safe of subway tunnel structure has a direct impact on the safety of urban rail transit,so it is necessary to inspect the rail transit structure regularly.In this paper,we used a robust detection method based on mobile laser scanning technology,which make the efficiency,high precision,full range and rich production urban rail transport structure detection become a achievement.In order to test this method,we conducted a series of experiments in virtual project,detecting deformation of urban rail transport structure.Finally,the results show that our proposed method get accuracy parameters of horizontal diameter,Joint opening measure,defect detection and 3D deformation,which can become the history archives of tunnel constructing.It will be the fundamental resources for performance assessment of urban rail transport operation,making the applied prospect become more ubiquitous.
