A study of a typical deep gorge wind field characteristics

The purpose of this paper is to investigate the wind field characteristics in deep gorge wind field to improve the safety and comfort of trains under the windy environment in deep gorge wind field. In this paper, a typical deep gorge wind field model is constructed to investigate the influence of canyon dimensions on the gorge wind field characteristics. The numerical simulation used in this paper was validated to be able to accurately simulate the structural characteristics of the gorge wind field by comparing it with the results of the previous mountain wind field experiments. The result shows that: the acceleration effect of airflow in the gorge increased significantly with the increase of the gorge height. The acceleration effect at the entrance decreases with the increase of the gorge width, while the acceleration effect at the center of the gorge remains the same.
