Application of 3D Laser Scanning Total Station in Tunnel and Exploration of Deformation Monitoring
By using a 3D laser scanner to collect data on tunnel construction,a certain amount of point cloud data can be obtained.By manually identifying and eliminating non-conforming point clouds,and then performing resampling and model construction,relevant cross-sectional information such as excavation,initial support,and secondary lining is extracted and compared to obtain corresponding result data.It provides accurate and reliable basis for optimizing construction plans,timely adjusting reserved deformation amounts,and eliminating construction quality problems such as insufficient thickness of secondary lining concrete pouring.At the same time,it provides efficient and comprehensive technical means for cost control,construction quality,and deformation monitoring of tunnel construction.In the temporary deformation monitoring of tunnels,the use of efficient and fast laser scanning technology will make the monitoring level more closely integrated with information-based construction.
