The study developed in this work is focused on constitutive modelling of saturated and unsaturated granular soils from the state parameters point of view. The Generalized Plasticity constitutive equation has been extended in order to reproduce stress-strain behaviour of granular soils with a single set of intrinsic model constants for different densities, confining pressures and saturation conditions.
