This document validates the Soft Soil Creep model in PLAXIS. The undrained triaxial creep behaviour of Haney clay is simulated, using the material parameters reported by Matsui & Abe (1988). The results are compared with test data provided by Vaid & Campanella (1977), including constant strain rate shear tests and undrained triaxial creep tests. An extensive validation of the Soft Soil Creep model is presented by Stolle, Bonnier & Vermeer (1997).
