| 摘 要： | 有关对填料为均质时和考虑路面材料及路基压实度分区时的沙漠公路路基边坡的稳定性分析，以及相关实体工程计算结果表明，与按均质填料情况相比，考虑路基上部及面层性质时的路基边坡安全系数略有增大，且填方高度越大其差异越小，其中边坡的坡率和填料的实际内摩擦角是边坡稳定性的主要影响因素，而填方高度的影响较小。

| Abstract: | This paper analyzes the slope stability of wind-blown sand subgrade when the fill is isotropic and the pavement material as well as the compactness zoning are considered. The results and the related engineering body calculation show that the safety coefficient of anisotropic slope is slightly larger than that of isotropic slope, and the higher the slope is, the smaller the difference is. Especially the ratio of slope stability, and actual internal friction angles of wind-blown sand are the main influencing factors of slope while the influence of fill depth is relatively less. |
