In order to prevent and control the snow drifting disaster along the Karamay-Tacheng Railway in northwest of Xinjiang, numerical simulation method was adopted to study the influence of different height and angle parameters of wind deflector on the snow flow field around a given railway embankment in 50-year recurrence period in this paper. The results show that increasing the angle between the wind deflector and the prevailing wind direction will weaken its effect on snow dispersion in the 50-year recurrence period. When the angle is set to 60°, the snow dispersion effect is the best. Increasing the height of the wind deflector will increase the coverage of the acceleration zone, which is more conducive to disperse snow flow and reduce the probability of snow particle accumulation. When the height is set to 2 m, it's a cost-effective solution.
