基于三维激光扫描技术的地铁隧道结构变形监测应用研究

本文将三维激光扫描监测技术应用于地铁区间隧道结构变形监测,取得了较好的效果。该方法首先采用三维激光扫描仪获取的高密度点云信息提取隧道结构信息;然后通过自动化处理软件实现点云数据的快速处理,自动提取环片的点云;最后利用提取的环片点云对环片错台、水平收敛等结构变形进行分析。本文通过对武汉某地铁项目施工中三维激光扫描应用案例介绍,说明了三维激激光扫描对隧道结构监测的优势。

Research on Application of Structural Deformation Monitoring of Metro Tunnel Based on 3D Laser Scanning Technology

n this paper, the three-dimensional laser scanning monitoring technology is applied to the deformation monitoring of subway tunnel structures, and good results have been achieved.The method first uses high-density point cloud information obtained by a three-dimensional laser scanner to extract tunnel structure information; and then realizes rapid processing of point cloud data through automated processing software, automatically extracts ring point cloud, and finally uses the extracted ring point cloud Analysis of structural deformation such as ring stagger and horizontal convergence.This article introduces the application case of 3D laser scanning in the construction of a subway project in Wuhan, and explains the great advantages of 3D laser scanning for tunnel structure monitoring.
