| Abstract: | In this paper, the strength characteristics of unsaturated loess are studied. Based on the general tri-axial test results the nonlinear relationship formula between suction strength and saturated degree is presented. The exponential function relationship between shear strength and water content of unsaturated loess are confirmed. |

| Keywords: | unsaturated loess general tri-axial test suction strength nonlinear relationship formula |
