Research on Disease Detection Technology of Operating Subway Tunnel Based on 3D Laser Scanning Technology
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.
