Abstract

The
Creep-SCLAY1S model is capable of simulating the anisotropic and rate-dependent
behaviour of soft soils. The mathematical formulation also includes the
possibility to model bonding and destructuration. Many constitutive models have
been proposed in literature to describe the behaviour of structured natural
clays. Most of the rate-dependent models were developed based on the Perzyna'
(Perzyna (1963) and Perzyna (1966)) overstress theory (e.g. Hinchberger &
Rowe (2005) and Zhou, Yin, Zhu & Cheng (2005)), with the disadvantage of a
difficult parameter calibration process (Karstunen & Yin (2010)). Another
approach consists in using empirical formulations, as for example the Soft Soil
Creep model available in the PLAXIS standard library. The Creep-SCLAY1S can be
considered a special kind of extended overstress model derived from an
empirical equation (Sivasithamparam, Karstunen & Bonnier (2015)).
