Application of 3D Laser Scanning Technology in Tunnel Overexcavation and Underexcavation Measurement
Tunnel overexcavation and underexcavation monitoring is an important and safety related task,and high-preci-sion advanced tunnel excavation monitoring methods are crucial.In this study,3D laser scanning technology into tunnel over-excavation and underexcavation monitoring work is introduced,the German Z+FIMAGER5010 3D laser scanner is used to obtain 3D coordinate data and information of the inner surface contour of the tunnel,and Amberg and Tianyou Intelligent Tunnel software are used for data processing.The results show that 3D laser scanning can obtain data accurately,efficiently,and comprehensively,and the data results can well reflect the situation of tunnel over and under excavation,which meets the measurement requirements of tunnel over and under excavation monitoring.The application of 3D laser scanning technology in tunnel over and under excavation measurement can effectively improve the efficiency and accuracy of tunnel monitoring operations,and can be widely applied in tunnel over and under excavation monitoring.
