| Abstract: | Deformation monitoring is indispensable to long-span bridges while open to traffic.This paper introduces the internal microcosmic measuring and its external macrocosmic surveying of the Third Bridge of Xiangjiang River in Xiangtan while open to traffic.It also indicates that synthetic surveying is an efficient approach to know about the state of the bridge.In addition,it provides the analysis of the applied model and the data precision of the macrocosmic surveying. |
