Abstract
Based on the transformed stress and the subloading surface concept, a new generalised critical state model with special focus on the volume change under general loading conditions, is presented in this paper. As existing test date show that not only the shear strength, but also the volume change of clays depend on the loading conditions, a new stress-dilatancy equation defined in the transformed stress space is established. Compare with the Cam-clay model, the proposed model only adds two new parameters. The proposed model can not only describe the strain-softening behavior of overconsolidated clays, but also takes into account the influence of intermediate principal stress on strength and deformation of clays.
