Study on Shear Stress‐Strain Model for Unsaturated Soil
Shear stress‐strain model of unsaturated soil plays an important role in its constitutive law, and it is very interesting but not well solved. In this paper, the deficiency of the traditional hyperbolic model for the unsaturated soil shear stress‐strain relationship is analyzed by employing half‐value‐strength index (HVSI). A new model with 3 parameters for unsaturated soil shear stress‐strain relationship is established based on the differential governing equation. Mathematical analysis shows that the 3‐parameter model can overcome the deficiency of the traditional hyperbolic model and has more extensive applications. Finally, comparisons between the traditional hyperbolic model, the new established model and laboratory tests are conducted, and the results show that the new model is more accurate than the hyperbolic model.
