摘要

The tests of shear strength of unsaturated loess under different water contents are performed with the tri-axial apparatus specially made for unsaturated soil. The test data show that the shear strength of unsaturated decreases with increasing water contents, the shear strength of unsaturated loess will be close to the minimum when the water content is saturated. As the water content increases, the suction and the safety factor of stability become smaller gradually. The loess slope will be destroyed when the water content comes to a certainty value.
