摘要：

With modified unsaturated soil triaxial apparatus, unsaturated soil shear strength of the tests under the condition of different water contents are done. Experimental results show that the matric suction exist in unsaturated soil and increases with the decrease of moisture content. And the shear strength of unsaturated soil is higher than that of saturated soil. Shear strength of unsaturated soil varies as the matric suction and water content. The shear strength increases when the matric suction increases. when soil tend to be saturated, the matric suction will tend to be zero. And the shear strength of unsaturated soil values gradually close to the strength of the saturated soil.
