Based on the 3D incompressibleequations and the standardturbulent model, taking numerical calculation as the main research method, the relative motion model of station-train was established, the air flow field environment that when a train (CRH2) ran in the intercity railway tunnel at a speed of 200 km per hour was simulated. The changing process of the train wind on the platform when the train passed through the platform was analyzed, the distribution characteristics of the train wind on the platform were discussed, according to the train wind reference standards, the safety avoidance distance of people on the platform had been worked out. The results show that: the gradient of the boundary layer wind speed close to the train wall is very large; the train wind near the tail of the train is the most unfavorable position; in order to keep the personal safe, protective measures should be taken when necessary.
