| In this study, experiments on the SWCC were performed in order to find out the characteristics of unsaturated soil and to analyze the stability of unsaturated weathered slopes with rainfall-induced wetting. Several soil types classified by mixture portion of clay (CH) in the weathered soil (SW) were used in experimental tests. To achieve the SWCC, the filter paper method was used on SW with varying clay contents. A tensiometer test was used for measuring wetting front suction of the soils in a laboratory with varying relative densities. Based on the experimental results, it is shown that the wetting front suction increases as clay contest of mixture soil increases : in particular, the wetting front suction increases sharply as the clay contents increase. It is also found that wetting front suction affects the initial wetting band depth and stability of the slope. |
