| Abstract: | Employing a phenomenological approach consistent with continuum mechanics of unsaturated soil,the shear strength behaviors of unsaturated soils in the counties of west north of Hubei province and Nanyang of Henan province are explored.The relationships of shear strength of unsaturated soils with water content and matrix suction are represented.Some experiences for solving the application of expansive soils in engineering are obtained. |

| Keywords: | unsaturated soil expansive soil shear strength of unsaturated soil triaxial test of unsaturated soil |
