The Response Analysis of the Vehicle-bridge System about Influence Factors

This article set up the practical space mode, with an example of a dual-line 32 m single box section beam on Beijing-Shanghai Railway Line. Considering the vehicle speed, the intensity of earthquake wave, the height of pier; the depth of soil as the influence factors, the dynamic response of the bridge was analyzed by the large finite element software ANSYS under seismic action. The impact about the dynamic interaction of the different influence factors affecting on the design of high-speed railway bridges was got which will provide reference and basis for the construction and design similar project.
