摘　　要：简述防雪栅栏对公路风吹雪雪害的防治原理,基于Fluent14.0软件,选取新疆塔城地区G3015,S201线典型路堤断面,针对特定的三维防雪栅栏,通过改变防雪栅栏至路堤水平距离、路堤高度、路堤边坡坡率及防雪栅栏的排数等参数,对防雪栅栏对路堤断面风雪流场的影响进行研究。The prevention principle of snow fence against snow drift disaster on highway was described,and then with Fluent 14.0 software,the typical section of embankment of Line G3015,S201 in Tacheng area,Xinjiang was selected to study the given three dimensional snow fence in such manner that the parameters,such as the horizontal distance between the snow fence and embankment,the height and slope ratio of embankment,and the rows of snow fence,were changed to find out the effect of snow fence on the wind and snow flow field of embankment section.
