摘　　要：为了研究吉林省公路风吹雪的分布特征,采用现场调研与Ansys Fluent软件仿真模拟相结合的方式,绘制吉林省公路风吹雪分布地图;以吉林省受灾最多的路基横断面形式为例,以主要地形区雪季平均风速为代表风速仿真模拟,结果表明:吉林省公路风吹雪分布特征的主要影响因素是风速。In order to study the distribution characteristics of snow drift on highways in Jilin Province,a distribution map is drawn by combining field investigation with Ansys Fluent software simulation.In this paper,the most affected subgrade cross-section is taken as an example,and the average wind speed in the snow season of the main terrain area is used as the representative wind speed for simulation.The results show that the wind speed is the main factor affecting the distribution characteristics of snow drift on highways in Jilin province.
