摘要
对三维激光扫描技术在隧道形变监测中的应用进行了初步研究。实验使用Leica Scan Station P40三维激光扫描仪对常州地铁1号线隧道进行扫描,将处理后的点云数据通过徕卡隧道形变监测系统进行隧道断面净空计算。将利用三维激光扫描技术得到的隧道断面成果与利用传统全站仪测量得到的隧道断面成果进行对比,讨论并分析三维激光扫描技术在隧道形变监测中的技术优势和存在的问题,对三维激光扫描技术在隧道形变监测中的应用具有指导意义。
This article contains a study in the application of three-dimensional laser scanning technology in tunnel deformation monitoring. Equipped with Leica Scan Station P40, the experiment is using point clouds to calculate the section clearance in the Metro channel in Changzhou city. Based on the comparison of outcomes from both laser scanners and traditional total stations, the author is able to discuss the technical advantages and existing problems of the three-dimensional laser scanning technology in the tunnel deformation monitoring leading to an instructive conclusion in the application of laser scanning technology in tunnel deformation monitoring.
