Abstract:
The shear strength formulae for unsaturated soils were divided into five categories, such as using soil-water characteristic curve, mathematical fitting, piecewise functions, total stress indicators and other forms. Characteristics and deficiencies of the current research on shear strength formulae for unsaturated soils were analyzed. The results show that some differences in mechanical significance exist between shear strength formulae based on the effective stress and shear strength formulae based on the two-stress state variables. Different expressions of suction strength lead to diversities of the shear strength formulae. True triaxial tests of unsaturated soils are urgent need to be carried out and strength theory of unsaturated soils satisfying the actual engineering stress conditions is to be established in order to improve the theoretical basis of unsaturated soils and accelerate the process of engineering applications.
