Abstract
Soft clays found in situ are often K0-consolidated. Due to this anisotropic consolidation history, the yield points identified from triaxial tests are not symmetric around the hydrostatic axis. In this paper the anisotropic consolidation of soft clay samples, with a wide range on friction angles, is simulated with a new constitutive model, called GUM, embedded in the multilaminate framework. The samples are subsequently reloaded along different stress paths in the p′-q-space, both in triaxial compression and triaxial extension. The global yield points predicted by the GUM model are compared with the yield surface predicted by the S-CLAY1 model and experimental data on reconstituted soft Finnish clays.
