摘　　要：三维激光扫描技术的出现,为边坡挡墙变形监测提供了新的监测手段,本文选用在测量领域中使用较广的脉冲式扫描仪,以监测某立交桥的边坡挡墙变形为实例,进行了点云数据采集。根据边坡挡墙变形监测的特点及数据处理的要求,使用机带软件RIEGL VZ-1000进行了点云数据预处理之后,再引入第三方点云处理软件Geomagic Studio和Geomagic Qualify,进行了数据处理及变形分析。通过研究,提出了基于三维激光扫描技术的边坡挡墙变形监测新方法。The emergence of three-dimensional laser scanning technology provides a new means to monitor deformation of slope and retaining wall. The paper uses the pulsed scanner which is widely used in measurement,we scan a slope and retaining wall of a bridge which is taking as an example and collect the point cloud data. According to the characteristics and requirements of the slope and retaining wall data processing,we use the RIEGL VZ-1000 which comes with the machine to finish point cloud data preprocessing,use the third-party point cloud processing software Geomagic Studio and Geomagic Qualify to process data and analysis deformation. After the research,we presented a new method to monitor deformation of slope and retaining wall based on 3D laser scanning technology.
