摘　　要：大型构件的变形监测是检验其设计和施工质量,为其安全运行提供科学依据的必要手段。以润扬大桥动静载实验为例,介绍利用GPS技术进行大型桥梁位移变形测量的方法和实现途径,从中总结出利用GPS技术对大型构件进行变形测量的基本流程。The aims of deformation monitoring of large structures are to verify the reliability of design and the constructional quality, and the results of deformation monitoring also indicate that the large structures are safe or not. GPS double differential positioning method can obtain millimeter level or higher precision, and has been widely used to deformation monitoring. Based on the static and dynamic load experiments of the Runyang Bridge, the methods and approach of displacement deformation monitoring for large bridges by using GPS techniques are introduced in this paper. The basic flow of deformation monitoring of large structures based on GPS techniques is summarized.
