Test data from isotropic consolidation tests and consolidated undrained tests with porewater pressure measurement have been used to form a constitutive model for the sand-bentonite buffer proposed for nuclear waste containment in Canada. The model develops functional expressions for p′, εv, q, εs, p′, εsand q, εvrelationships in the buffer. Predictions for constant-p′ tests are compared with experimentally measured values.
