Based on some soil samples with different sediment percentage of wind-blown sand, the paper analyzes the particle compositions of va-rious sand samples nonuniform coefficient and gradation composition, and according to various experiments, the physical and mechanical charac-teristics of wind-blown sand for highways across the desert. This paper can provide basis for applying wind-blown sand as subgrade materials of highways across the desert.%以穿沙公路风积沙中掺加不同含泥量的土样为研究对象，分析了不同风沙试样的颗粒组成、不均匀系数及级配组成等，并通过各项试验研究，探讨了穿沙公路风积沙的物理特性和力学特性，为风积沙广泛应用于穿沙公路的路基材料提供了相关的科学依据。
