摘要
针对现行隧道断面检测与监控量测方法存在的问题,引入三维激光扫描设备开展隧道断面检测与监控量测。文章通过分析三维激光扫描技术在隧道中检测时产生的误差成因,对设备的标称精度与隧道测量精度不匹配的问题进行了研究。通过开展同位、异位监控量测试验,提出了隧道三维激光扫描设备精度验证方法、条件,并对三维激光扫描的隧道断面检测与监控量测应用提出了一些建议。
In view of the problems existing in the current tunnel section detection and monitoring measurement methods,the 3D laser scanning equipment is introduced to carry out the tunnel section detection and monitoring measurement.Based on the analysis of the error cause of the 3D laser scanning technology in tunnel detection,the problem of mismatch between the nominal precision of equipment and the measurement precision of tunnel is studied.By carrying out monitoring and measuring experiments at the same position and the other position,the method and conditions for verifying the accuracy of 3D laser scanning equipment in tunnel are put forward,and some suggestions on the application of 3D laser scanning in tunnel section detection and monitoring measurement are put forward.
