Occurrence and development of winter-time natural convection cooling effect in the fractured-rock embankment of Qinghai-Tibet highway were investigated using the governing equations based on air-flow function for natural convection in porous media with variable permeability.

通过变渗透率多孔介质流函数控制方程，分析了青藏公路碎石路堤冬季自然对流降温效应的发生和演化过程。结果表明：公路碎石路堤冬季自然对流降温效应从边坡区域最先开始形成，并随着冬季路面温度下降而逐渐向路堤中间区域发展。

Dapingzi highway tunnel is located in sound potash granite covered by debris.The overburden of the tunnel is relatively thin and the bias is great. In entrance zone,slope surface is covered with thick deluvial,colluvial,alluvial debris,resulting in difficult tunneling condition.
