불포화 풍화토의 $K_0$ 압밀 삼축압축실험

[ $K_0$ ] consolidated triaxial tests for unsaturated weathered soils

In order to predict the stability of slopes, it is important to evaluate shear strength of unsaturated soils. The triaxial tests were performed under $K_0$ conditions for unsaturated soils and the results were compared with those for saturated soils. In unsaturated soils, the secant modul and the shear strengths are larger than those of saturated soils because of matric suctions. However the shear strengths were not affected severely by stress conditions at consolidation.
