Constitutive properties and modelling of silty soils
Luleå tekniska universitet.

Abstract [en]

brief description of the characteristics of silty soils is presented. Results are given from undrained triaxial tests on Swedish silts, which show contractant behaviour at small strains whereas the behaviour becomes dilatant close to the critical state. The undrained effective stress path then changes direction at the critical state line which will be followed while the shear strain increases. A simple constitutive model was adopted to predict the transitional behaviour. The model, which is based on the Cam-Clay concept, includes shear hardening in addition to volumetric hardening. Comparisons of predicted and experimental results in the undrained case show a very good agreement, in particular with respect to the transitional behaviour represented by a ``hook'' in the effective stress path.
