In order to improve the large deformation and vibration of the bridge under the dynamic action of wind, the stability of the bridge structure and the safety of the train operation are improved. A modeling method for dynamic feature change based on wind load is proposed. The dynamics characteristic model of bridge is established firstly. The modal synthesis method is adopted to analyze the whole vibration of the bridge structure, to greatly reduce the dynamic degree of freedom as well as the deformation and vibration of the bridge, and improve the stability and safety of the bridge structure. Then the dynamic characteristics of the bridge under the wind load are analyzed. The experimental results show that the proposed method can improve the stability of bridge structure and reduce the deformation and vibration of the bridge caused by wind power.
