| Research Abstract |
This study obtained as followings; SWCC is useful to conduct effective stress analysis for unsaturated soils. Collapse behavior performed during seepage and applying of suction that influence to unsaturated soil properties. At cyclic loading triaxial tests under undrained conditions, excess pore-water pressure occurred a few. Other hands, unsaturated soils due to seepage described that excess pore-water ratio approached to 1.0 and took a failure as fully saturated soil. Also suction control technique was developed through this test program.
