摘要: 牧区道路是一种比较特殊的道路形式,易受雪害和沙害的影响。文章利用有限元的方法分析了挡雪墙和挡沙 墙、防雪栅板、导风板前后的风速场,模拟风雪流和风沙流在遇到以上防雪挡沙结构物时的速度场,从而提出牧区 道路各种防雪挡沙结构物的合理位置、高度及形式

关键词: 有限元, 风雪流, 风沙流, 挡雪防沙结构物

Abstract: The road in pastoral area is a special kind of highway, which is ready to suffer from snow hazard and sand hazard. Based on the analysis of the speed of wind blowing across The Snow Protection Facilities And Sand control Facilities with FEM, the speed field of Snow-bearing wind and Sand-bearing wind was simulated, then the reasonable position, height and modality of the protection facilities were proposed

Key words: finite element method, snow-bearing wind, sand-bearing wind, the snow protection facilities and sand control facilities
