摘　　要：针对导风式防眩板这一公路风吹雪雪害防治措施,基于交通设施诱发公路风吹雪雪害形成机理,采用计算机仿真方法,选择整体式路堤这种典型的路基断面形式,定量分析不同的风速、导风式防眩板设置参数下整体式路堤断面的风速流场特性及影响关系,为多雪地区公路路基断面及防眩设施优化设计与养护提供科学的理论依据。Ventilated anti-dazzle board is a preventive measure for snow drift hazard on highway. Based on the formation mechanism of snow drift hazard on highway induced by traffic facilities, by means of computer simulation method, the typical subgrade section of integral embankment is selected to quantitatively analyse the wind velocity flow field of the integral embankment section under different wind speed and ventilated anti-dazzle board setting parameters, which provides scientific theoretical basis for optimization design and maintenance of highway subgrade section and anti-dazzle facilities in snow area.
