| 摘 要： | 常见的地铁隧道病害有渗漏水、裂缝、错台、侵界等,这些地铁隧道病害的存在会对隧道的安全使用造成不好的影响.因此,需要定期对隧道的病害进行检测,并进行相应的修复.对于地铁隧道病害检测,常用的方法有人工巡检方法、全站仪方法等,这些方法效率低下且采集信息量有限.针对这些问题,使用一种自主研发的移动三维激光扫描系统进行隧道检测....

| Abstract: | The common subway tunnel diseases include water leakage,cracks,wrong platform,boundary invasion,etc.The existence of these subway tunnel diseases will have a bad impact on the safe use of the tunnel.Therefore,it is necessary to detect the tunnel diseases regularly and repair them accordingly.For subway tunnel disease detection,the common methods include manual inspection and total station,etc.,which are inefficient and have limited information collection.To solve these problems,a self-developed mobile 3D laser scanning system is used for tunnel detection.With the cooperation of 3D laser scanner and rail car system,subway tunnel data can be collected quickly,accurately and in large quantities.According to the application analysis of practical cases,the mobile 3D laser scanning system can quickly and accurately identify leakage,cracks and other diseases,and calculate and analyze the wrong station,boundary-crossing and other diseases. |
