摘要
针对挡雪板这一公路风吹雪的灾害防治措施,简要论述公路风吹雪形成机理和挡雪板的防雪原理。基于CFD(计算流体软件)Fluent分析,选择路堤这种典型的路基断面形式,结合塔城地区公路风吹雪害防治工程项目,运用欧拉-欧拉数值的仿真方法,对挡雪板不同设置方式及防雪效果的影响进行研究。模拟雪灾发生与防治实际过程,从而为挡雪板及其他防雪工程设施的设置提供切实可行的分析方法。
It briefly discusses the forming mechanism of snow drift and the working mechanism of snow protection facilities ,focusing on snow protection slab—a facility for road snow drift protection .Based on CFD（Computational Fluid Dynamics） Analysis ,the paper chooses embankment ,a typical road form with subgrade section ,as the research subject ,and takes account of the road snow drift protection program in Tacheng prefecture .It analyses the snow protection effects of different slab setting styles with the help of Euler‐Euler numerical simulation .As the simulated snow protection effect is very close to that in real ,the research provides a practical and analytic guidance for the setting of snow protection slabs ,as well as for the setting of other snow protection facilities .
