摘　　要：分析了风吹雪灾害形成的因素和机理,并结合黑龙江省4条主要公路的风吹雪灾害调查数据,对该省公路风吹雪灾害的分布特征进行了分析。结果指出,气候和地形条件,特别是公路路线走向、路基横断面形式以及路基高度对风吹雪灾害的形成具有主导作用。The cause and mechanism of snowdrift formation were analyzed. Combining with investigated data of snowdrift disaster on four main highways in Heilongjiang Province, the distribution characteristics of the snowdrift in the prorince were discussed. Result shows that the climate and topography, specially the trend of the highway line, the cross section and height of the roadbed have predominant effect on the snowdrift disaster.
