3术语和定义

风吹雪blowing and drifting snow

降雪时或降雪后，风力达到一定强度时，风吹扬雪粒形成风雪流。从风雪流的形成到积雪的全过程（雪粒子的蠕移、跃移、悬移﹑沉积）称为风吹雪。

公路风吹雪雪害blowing and drifting snow disaster on highways

风吹雪对公路通行造成危害时称公路风吹雪雪害，其表现形式有两种：一是降低能见度，影响驾驶员视线，形成视程障碍；二是路面积雪，影响车速甚至阻断交通，形成通行障碍。

低路堤low embankment

在正常的地质与水文等自然条件下，高度小于1.0m的路堤。

中路堤medium embankment

在正常的地质与水文等自然条件下，填筑高度介于1.0m～3.0m之间的路堤。

高路堤high embankment

在正常的地质与水文等自然条件下，填筑高度大于3.0m的路堤。
