• 摘要： 旨在调查研究三维激光扫描技术在地铁隧道测量的应用方向和技术成熟度，为其在隧道工程测量的推广应用提供指导。近几年大量文献针对三维激光扫描技术在地铁隧道测量的应用进行了研究，本文综合分析了当前各研究方向实现方法、精度、作业效率及实际应用效果，表明：（1）在隧道中轴线提取、纵横断面及限界测量、调坡调线、三维建模等方面三维激光扫描技术应用成熟，但是作业效率需进一步提高；（2）在断面变形与收敛分析方面，激光扫描技术优势显著，得到较广泛的应用，编入到2016 版《建筑变形测量》规范中；（3）在隧道裂缝和渗水检测方面有所尝试，但精度效率有待考证。
• The aim is to investigate and study the application direction and technical maturity of 3D laser scanning technology in subway tunnel measurement, and to provide guidance for the popularization and application of tunnel engineering measurement. In recent years, a large number of literatures have studied the application of 3D laser scanning technology in subway tunnel measurement, and this paper comprehensively analyzes the current research direction implementation methods, precision, operational efficiency and practical application effect, indicating: (1) in the tunnel axis extraction, crosssectional and limit measurement, slope adjustment line, 3D modeling and other aspects of 3D laser scanning technology application mature, but the operating efficiency needs to be further improved; (2) In the aspect of section deformation and convergence analysis, laser scanning technology has significant advantages, has been widely used, and is incorporated into the 2016 edition of the “Building Deformation Measurement” specification; (3) There are some attempts in tunnel cracks and water seepage detection, but the accuracy efficiency has yet to be verified.
