摘要
文章以深圳某跨街公园天桥项目为例,从数据预处理、精度分析、断面提取与变形分析等方面研究了三维激光扫描技术在既有地铁隧道变形监测中的应用,并将变形监测结果与传统自动化变形监测结果进行了对比分析,监测结果基本一致。由此可见,在具体实践中,结合应用两种监测技术可全面掌握地铁隧道变形情况,为后续施工提供可行性指导。
Taking the overpass project of a cross-street park in Shenzhen as an example,this paper studies the application of 3D laser scanning technology in the deformation monitoring of existing subway tunnels from the aspects of data preprocessing,accuracy analysis,section extraction and deformation analysis.The deformation monitoring results are compared with the traditional automatic deformation monitoring results,and the monitoring results are basically the same.It can be seen that the combination of the two monitoring technologies can fully grasp the deformation of the subway tunnels in the specific practice,which can provide feasible guidance for the subsequent construction.
