The research of monitoring model for bridge running

The model monitoring the safety of long-span bridges should be established considering its dynamic characteristics. This paper discusses using adaptive Kalman filter to establish the dynamic monitoring model of long-span bridges, considering the wind speed, temperature, traffic flow and other outside influences as the state factors of deformation of a bridge, the deformation rate components of the bridge and control values. The analysis of Nanjing Second Yangtze River Bridge shows that the dynamic monitoring model has better results and applying value.
