A Three-Dimensional Unified Hardening Model for Anisotropic Soils
Based on the UH (unified hardening) model a new anisotropic constitutive model for anisotropic soils is presented in a new anisotropic transformed stress space. An anisotropic peak strength Mα is firstly introduced to represent the inherent anisotropy associated with particles' orientation distribution. An anisotropic transformed stress tensor σ˜ija is proposed by incorporating Mαwith the original transformed stress tensor σ˜ij. The failure criterion and the stress-strain relationship for anisotropic soils are interpreted in the same constitutive framework. The capabilities of the proposed model are illustrated through comparisons of model simulations with experimental data. The basic soil parameters can be determined from the conventional triaxial compression tests on vertical specimens and horizontal specimens.
