摘要：
Based on three unsaturated soil shear strength tests, it is found that the Mohr-Coulomb failure surface is a ruled surface. The improved Mohr-Coulomb failure theory is suggested to describe the failure surface. And then, to get the index of the Mohr-Coulomb failure theory, equal cohesion-suction curve and the equal fraction angle-suction curve are suggested. Finally, several shear strength theories are evaluated by drying soils and saturated soils. Improved Mohr-Coulomb failure theory can describe the failure of unsaturated soils.
