The Sydney Soil Model is formulated within the framework of Critical State Soil Mechanics. In the proposed model, the behaviour of a soil is divided into two parts, that at a reference state and that attributed to the influence of soil structure. The reference state behaviour is formulated according to soil properties at the critical state of deformation based on the concept of plastic volumetric hardening. The influence of soil structure is introduced by formulating the variation of the additional voids ratio, associated with soil structure, for any general stress or strain path. The proposed model is employed to simulate the behaviour of a natural sensitive clay and a dense sand under conventional undrained triaxial tests. It is shown that the model can provide good simulations for the behaviour of structured soils.
