中文摘要：

采用数值模拟方法,对一CRH2型列车在高速铁路隧道以时速200 km运行时的环境进行了模拟,当列车经过站台时,对站台上的列车风的变化过程进行了分析,讨论了站台上列车风的分布特性,并确定了站台人员的安全避让距离.结果表明：紧贴列车壁的边界层风速梯度很大;列车尾部为风速最不利位置;为确保人员的安全,必要时应采取保护措施.

英文摘要：

Based on the numerical simulation method, the environment where a train of the CRH2 type ran in the high-speed railway tunnel at a speed of 200 km per hour was simulated . And when the train passed the platform, the changing process of the train wind on the platform was analyzed, the distribution characteristics of the train wind on the platform were discussed and the safety of hazards distance of people on the platform was determined. The results showed that： the gradient of wind speed of layer close to the train wall boundary is very large ;the train wind near the tail of the train is the most unfavorable position ; protective measures should be taken to ensure people＇s security if necessary.
