摘　　要：通过室内试验利用有机材料、粘性土、和荷兰淤泥改善非饱和砂的表观粘聚力 ,选择五种不同类型的砂、有机材料、黑淤泥、斑脱土和高岭土做为试验材料研究非饱和状态下砂的粘聚征 ,试验结果表明 ,在非饱和状态下 ,砂会表现出一定的粘聚力 。The paper focuses on the apparent cohesion of the unsaturated sand. The efforts have been done in the laboratory to use organic materials, clay, and Dutch black peat to improve the apparent cohesion of the unsaturated sands. Five types of sand, organic material, black peat, bentonite and kaolinite have been chosen to probe the cohesive characteristics of sand under unsaturation state. The test results shown that the sand shows some cohesion under unsaturation state and some material shows a significant increase in apparent cohesion of unsaturated sand.
