| In South Korea, many weathered soil slopes are composed of soil mixtures with certain amount of clay fractions in natural soil deposits. Accordingly, it is very important to analyze that effect of the fines on the stability of unsaturated soil slopes. In this study, five different soil types classified by mixture portion of fines were used and experiment on the soil-water characteristic curve tests (SWCC) using GCTS (Geotechnical Consulting and Testing Systems) pressure plate were performed in order to analyze the stability of unsaturated soil slopes. Based on the infiltration analysis which contains SWCC test result by the SEEP/W, it is shown that the increasing rate of the wetting band depth was decreased as the fines content and the relative density were increased. According to the stability analysis result of the unsaturated soil slopes through the SLOPE/W, it is found that the transition from the wetting band depth to the variation of strength parameters which affect the stability of unsaturated soil slopes appears to occur around $10sim15%$ of clay contents in the mixtures. |
