Fluent numerical simulation was conducted on two types of half cut road conditions on high-ways to analyze the influence of wind direction angle on the concentration of snow accumulation in half cuts.The distribution pattern of snow accumulation in half cuts was obtained,providing theo-retical reference for highway route selection and design.The results show that as the wind angle increases,the overall snow concentration in the leeward half of the road cutting shows an increas-ing trend.When the wind direction angle is 90°,the snow concentration is the highest,reaching 72.21 Kg/m3,forming a serious wind snow disaster;The overall concentration fluctuation trend of the windward half cutting is within 5 Kg/m3,and the snow concentration is below 20 Kg/m3,which is not enough to form a wind snow disaster.When designing the route of highways in areas with frequent wind and snow disasters,the angle between the highway and the main wind direc-tion should be reduced to reduce the occurrence of wind and snow disasters.
