Zusammenfassung:The elastoplastic model in the deviatoric stress space is constructed to describe the cyclicundrained creeping behaviour of soft clays under cyclic stress by using Mises yield criterion and the concept ofa field of hardening moduli. Furthermore, the effect of model parameters on the deformation is studied, anda method is given to determine quantitatively model parameters from results of cyclic triaxial tests of thesaturated soft clay.
