摘　　要：目前三维激光扫描技术已经广泛应用于建筑领域,但是在桥梁工程中、尤其是在大型斜拉桥的施工监测量测过程中应用甚少。项目基于某新建高速公路大型斜拉桥进行施工期三维扫描应用,对梁底线型偏差、锚点位置偏差、合龙段进行了量测。获取过程简单迅速、结果精度较高,为今后同类型项目提供了示例参考。3D laser scanning technology has been widely used in the field of architecture,however, it is rarely used in bridge engineering,especially in the construction monitoring of large cable-stayed bridge. Based on the 3D scanning application of a large-scale cable-stayed bridge on a new expressway during construction period,this project measures the beam bottom line deviation,anchor position deviation, and closure section. The process is simple and rapid with high accurate accuracy,which provides an example reference for similar projects in the future.
