Train-Bridge Interaction on the High-Speed Railway Bridge in Antoing

摘要

The study of train-bridge interaction is important for the design of the bridge, especially the serviceability state. Interaction models will also provide information about the comfort of the passengers and the safety of the train vehicles during the passage of bridges. The bridge structure, the rail support, the train speed, the train itself, including the linking and suspension system, can influence the int eraction between bridges and passing trains. The results of a dynamic experiment on the Antoing bridge, located on the high-speed railway line between Paris and Brussels are reported. Displacements, accelerations and strains were measured during several passages of Thalys trains with articulated vehicles. The measurements are compared with the predictions of different numerical models.
