摘要：
A constitutive model based on the critical state concept and viscoplasticity is developed. The model is capable of predicting primary and secondary compression, including the effects of over-consolidation ratio and load increment ratio on these phenomena. The model can also predict the effect of strain rate during undrained shear tests, drained and undrained creep as well as typical stress paths followed in conventional triaxial tests. All rate effects are introduced by a single parameter-the coefficient of secondary compression. The traditional concepts of primary consolidation, secondary compression and overconsolidation ratio are discussed.
