- Description
- This paper presents an advanced constitutive model for unsaturated soil based on sub-loading surface plasticity. The proposed model is capable of modelling typical hydro-mechanical behaviour of soils compacted to different initial densities. Bishop's effective stress and the effective degree of saturation are selected as two fundamental constitutive variables in the proposed constitutive model. A sub-loading surface and a unified hardening parameter are introduced into the stress-saturation modelling framework to interpret the effects of initial density on hydro-mechanical behaviour of compacted soils. The proposed advanced unsaturated soil model is then validated against a number of experimental results reported in the literature.
