摘　　要：将三维激光扫描技术应用于地铁隧道调线调坡断面测量中,详细阐述了基于此技术的测量作业流程,包括控制网的测设以及点云数据的采集与处理等。以常州轨道交通1号线沿江城际站-科教城南站区间右线隧道断面测量工作为例,将三维激光扫描断面测量成果与人工实测成果进行对比,说明采用三维激光扫描技术能够保证测量精度,可满足地铁隧道调线调坡断面测量的需求。The three dimensional laser scanning technology is applied in the subway tunnel section measurement for the adjustment of route alignment and gradient.The measurement process based on this technology are stated in detail,including the designing and measuring of the control network,the collecting and processing of the point cloud data and so on.Taking the subway tunnel section measurement of the right channel of the Yanjiangchengji Station-Kejiaocheng South Station of Changzhou Metro Line 1 for example.Comparing the three dimensional laser scanning section measurement results with the results measured artificially,indicating that the measurement accuracy can be guaranteed by using the three dimensional laser scanning technology and can reach the requirement of the subway tunnel section measurement for the adjustment of route alignment and gradient.
