| Abstract: | 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. |

| Keywords: | numerical simulation train-induce airflow moving mesh safe distance |
