In order to make the bridge finite element model more accurately and effectively reflect the state of the real bridge, this paper uses the dynamic response of the on-site structural vibration frequency and static load and strain, and proposes a method of combining static and dynamic forces to construct the objective function for optimal analysis. The finite element model of the approach structure of the Yihe Super Bridge has been corrected. By using the “ANOVA” method to find out the significant parameters, and then according to the actual situation of the project, the elastic modulus of concrete, the thickness of the bridge deck pavement, the concrete bulk density and the moment of inertia of the beam section are selected as the parameters to be corrected for the structure.
