摘要路堤边坡坡度是影响风吹雪区域路堤积雪的重要因素，利用现场模型试验以及流场数值模拟的方法，研究边坡坡度对路堤积雪影响规律，分析积雪形成机理。结果表明：路堤周围积雪范围与流场风速减弱区域存在较好的对应关系，但并非定量对应，用流场中风速减弱区域简单地定量判断积雪范围的方法误差较大；迎风边坡坡度的改变对路堤周围积雪分布影响较大，较缓的迎风边坡坡度将有效地减小路堤周围积雪量和积雪范围，路面更不易形成积雪，可以减小风雪流对路堤工程的危害；背风边坡坡度的改变对路堤周围积雪影响较小，路堤设计时可作为次要因素考虑；根据试验和模拟结果得出路面不易积雪的临界边坡坡度在40º和45º之间，保守起见，建议工程应用中取40º为路面不易积雪的临界边坡坡度。

Abstract：Side slope inclination of embankment is an important factor to affect embankment snow cover in wind-blown snow area. Here, field model tests and flow field numerical simulation method were used to study the influence law of side slope gradient on embankment snow cover, and analyze snow cover formation mechanism. The results showed that there is a good corresponding relationship between snow area around embankment and flow field wind speed weakening area, but it is not quantitative; the method of simply quantifying snow area by using the wind speed weakening area in flow field has a larger error; the change of windward side slope inclination has a larger effect on distribution of snow around embankment, a gentler windward side slope inclination effectively reduces the amount and range of snow around embankment, and the road surface is not easy to form snow cover to reduce the damage of wind and snow flow to embankment engineering; the change of leeward side slope inclination has a smaller effect on snow cover around embankment, it can be considered as a secondary factor in embankment design; according to test and simulation results, the critical side slope inclination for the road surface being not easy to form snow cover is between 40° and 45°; for the purpose of conservation, 40 ° should be taken as the critical side slope inclination for the road surface being not easy to form snow cover.

Key words： drifting snow side slope of embankment field model test numerical simulation
