Visual Monitoring Technology of the Tunnel 3D Laser Scanning and Engineering Applications

Abstract:

Tunnel monitoring and measurement is a very important part of the tunnel construction safety andit is one of the important contents of tunnels on Railway Passenger Dedicated Lines segment acceptance, Its purpose is through the tunnel clearance convergence and settlement observation,to analysis data, optimize tunnel construction and design, and determine a reasonable safety step and support time, protect tunnel construction and operational safety, Although the domestic and foreign on tunnel monitoring measurement work are very seriously, but at present the requirements of monitoring level and information construction are far away. This article based on 3D laser scanning technology, proposed tunnel 3D laser scanning measurement and data visualization technology, through the engineering application and practice, the results show that the technique can be real-time, accurate and comprehensive to get the deformation data of tunnel space,and can analysis and counter-analysis the deformation of tunnel construction, it has greatapplication value of engineering for early warning forecast the risk and guidingtunnel construction.
