摘　　要：基于计算流体力学软件Fluent,对武汉站高速列车过站列车风进行了数值模拟。展示不同部位的列车风分布形态,获得了列车风的空间分布特性;结合现有相关资料,确定了站台安全退避距离;分析了结构物受到的列车风风荷载作用。Based on Fluent soft platform, train-induced airflow of Wuhan railway station was simulated by computational fluid dynamics method. Configuration of train-induced airflow at different positions of the train was illustrated, and the distribution characteristics of train-induce airflow had been obtained. With criteria in some references, safe distance on the platform had been suggested. At last, the wind load according to the train-induced airflow on the structure was analyzed.
