Abstract

Experimental validation is a precondition for dynamic simulation of high-speed train-track-bridge interaction system to be applied to railway engineering in the field. The paper first presents an onsite experiment of the train-track-bridge interaction dynamics carried out on the Beijing-Tianjin high-speed railway, and then the experimental results are used to validate the train-track-bridge interaction simulation software (TTBSIM). There is a good correlation between the calculated results and the measured data. As a case study, the Yellow River Bridge in the Beijing-Shanghai high-speed railway is studied, from modelling of the bridge structure to evaluating the dynamic performance of the train-track-bridge interaction system under the CRH 3 EMU passing through at speeds of 250-375 km/h. The calculated and measured results are also compared in the case of such a large steel bridge under high-speed moving train, demonstrating the effectiveness of the TTBSIM simulation for dynamic evaluation of complex bridge structures in high-speed railways.
