摘要：In order to ensure the safe operation of the bridge, it is very necessary to establish real-time monitoring system on some extraordinary large-scale bridges. In this paper, the prestressed concrete continuous bealm bridge is taken as the research object. Firstly, ANSYS is used to establish the initial finite element model according to the design data of the bridge, and then update the calculation model to conform to the actual state of the structure. After that, the analysis of mechanical performance under design load is carried out to provide a theoretical basis for the optimal placement of sensors. Finally, the bridge real-time monitoring system is set up and the collected monitoring data (displacement, strain, acceleration, etc.) is taken a statistical analysis, for the purpose of making a preliminary judgement on the actual operation of the bridge, and being considered as the theoretical basis and database of real-time monitoring system for follow-up study.
