摘要：Based on a large span continuous rigid frame bridge in Chongqing, this paper studies the bridge linear, the vertical displacement and offset of the pier and the deformation of the expansion joints. Firstly, the deformation data of the bridge was artificially measured. And then, calculates the theoretical values of the bridge deformation with finite element software named Midas. Finally, the author compares and analyzes the theoretical data and practical data on bridge linear, the vertical displacement and offset of the pier and the deformation of the expansion joints. It shows that the bridge is under normal working condition. The indicators of monitoring large span continuous rigid frame bridge are completed and the convenient evaluation methods of the working condition of large span continuous rigid frame bridge are put forward.
