| Abstract: | The improved Triaxial Apparatus for unsaturated soil was used to test and study the relationship of matrix suction and water content under various confining pressures. And based on the test results both soil-water characteristic curves and confining-matrix suction curves have been plotted. The paper has analyzed the law of the curves and made adapting of the function between them. The paper has also calculated and predicted the permeability coefficient and the shear strength of unsaturated soil using the curves respectively. |
| Keywords: | unsaturated soil matrix suction water content soil-water characteristic curve adapting permeability coefficient shear strength |
