Abstract: A simplified model of a high-speed train breaking into gorge wind field is constructed, and the grid-independence validation was carried out to illustrate the correction of the grid used in the simplified model. The model is used to study the flow field around the train and its aerodynamic response characteristics when the train break into the deep gorge wind field. An in-depth study was conducted to investigate the influence of the location where the train passes through the deep gorge wind field on the diffraction characteristics of the flow field around the train and the aerodynamic loads characteristics. The results show that: due to the acceleration effect of the gorge, the train’s aerodynamic loads is larger when the train breaking into the deep gorge wind field at the entrance of the gorge, and the side force coefficient and overturning moment coefficient of the head car increase by 16.41% and 15.44% compared with that at the center of the gorge. The installation of windbreaks did not change the flow field characteristics when the train enters the gorge, but it can significantly reduce the aerodynamic loads. The side force coefficient and overturning moment coefficient of the head car are reduced by 80.1% and 75.7% respectively after the installation of the windbreak, which greatly ensures the safety of train operation.
