英文摘要	Aeolian sand is widely distributed worldwide from the Middle East to sub-Saharan Africa, from Central Australia to Western America: it can be seen everywhere. The California bearing ratio (CBR) is one of the most commonly used methods of evaluating the strength of a sub-grade soil, sub-base, or base course material both for designing and determining the thickness of highways and airfield pavements and for measuring the load-bearing capacity of soils used in building roads. This paper aims to test different moisture contents, mud contents, and gradations that affect aeolian sand strength and bearing capacity using the CBR method. Using sand samples collected in the Mu Us Desert in the northwest of China, a series of laboratory tests have been carried out to test the influence of moisture content, mud content, and dry density on the soil. The optimum moisture content of aeolian sand in the Mu Us Desert is approximately 10 - 12%. CBR increases with increasing moisture content before Optimum Moisture Content and decreases with increasing moisture content after Optimum Moisture Content. The Optimum Mud Content of aeolian sand is 10 - 40%; before optimum mud content, CBR increases with increasing mud content; after optimum mud content, CBR decreases with increasing mud content. CBR increases with increasing dry density of aeolian sand; CBR decreases with decreasing dry density of aeolian sand. With fixed coarse particle content, CBR increases with increasing fine particle content of aeolian sand before optimal mud content; CBR decreases with increasing medium particle content of aeolian sand after optimal mud content. When the moisture content reached OMC, it was easier to compact aeolian sand, the density of sand reached maximum dry density, and the particles were more difficult to move; therefore, shear strength reaches the maximum and CBR reaches the maximum accordingly.
