摘　　要：随着软硬件技术越来越成熟,三维激光扫描技术的用途日益广泛,已从文物扫描、模型复制推广到精密工程测量领域。本文以城市轨道交通建设项目为例,介绍了地面三维激光扫描技术在工程几何形变监测中的应用情况,并在测量效率、测量精度、数据全面性等方面与传统测量方式进行了比较。通过对比,三维激光扫描方法可用于进行隧洞拱顶沉降监测、平面位移监测和收敛测量等工作,效果良好。With the development of software and hardware technology, 3D laser scanning technology has been widely used. It has been extended from cultural relic scanning and model replication to precision engineering surveying. Taking the construction project of urban rail transit as an example, this paper introduces the application of ground 3D laser scanning technology in geometric deformation monitoring, and compares with traditional measurement methods in measurement efficiency, measurement accuracy and data comprehensiveness. By contrast, the 3D laser scanning method can be used for tunnel crown settlement monitoring, plane displacement monitoring and convergence measurement, and its effect is good.
