摘要: 地铁运营阶段对隧道结构的变形监测保证了地铁运行的安全。现阶段我国地铁隧道监测主要采用传统的全站仪等设备进行人工测量,该方法布设的变形监测点有限,且监测过程缓慢,难以全面反映隧道结构的整体变形特征。本文将移动式三维激光技术引入地铁隧道监测,采用推行式扫描方法快速获取隧道完整结构信息,自动化后处理软件全面监测隧道结构变形信息。该方法在满足监测精度要求的情况下,实现了地铁隧道快速、全面、可靠的结构监测结果。

Abstract: The deformation monitoring of the tunnel structure during the operation phase of the subway ensures the safety of the subway operation. At present, the monitoring of subway tunnels in China mainly uses traditional total station instruments and other equipment for manual measurement. The deformation monitoring points laid by this method are limited, and the monitoring process is slow, which is difficult to reflect completely the overall deformation characteristics of the tunnel structure. In this paper, mobile 3D laser technology is introduced into subway tunnel monitoring. The implementation of the scanning method is used to quickly obtain the complete structural information of the tunnel. The automated post-processing software is used to comprehensively monitor the deformation information of the tunnel structure. Experiments show that the method can achieve rapid, comprehensive and reliable structural monitoring results of metro tunnels under the condition of meeting the monitoring accuracy requirements.

Key words: tunnel monitoring, total station, mobile 3D laser scanner, structural deformation, subway
