The complex dynamic behavior brings challenges for investigating the ground vibration induced by trains passing through bridges, in which accurate modelling and a large amount of field data are required. To better understand and predict the ground vibration induced by high-speed trains passing through bridges, it is necessary to collect more field test data as well as to develop more accurate models and computational methods. In this study, a two-dimensional (2D) wheel-rail-bridge model was first constructed to determine the forces on the bridge pier, and these forces were then applied to the pier-ground finite element model to capture the ground vibration response. The simulated RMS acceleration and magnitude of acceleration were in good agreement with the field measured results, and the errors were within the acceptable range, which validated the effectiveness of the two-step method proposed in this study. The ground vibration response under various soil conditions was analyzed with the validated numerical model. The proposed method provides a reference for the prediction of ground vibration induced by high-speed trains passing through bridges and for the environmental protection.
