Constitutive Modeling of Cemented Sands Using Critical State Soil Mechanics and Generalized Plasticity Concepts

摘要：

　　In present research,a constitutive model is developed for prediction of the mechanical behavior of saturated cemented sands according to generalized plasticity and critical state soil mechanics concepts.The model is based on differences between normal consolidation curves of cemented and uncemented soil in elnp space.In order to consider the effects of cementation,six new parameters are added to the generalized plasticity model proposed by Manzanal et al.1.Deviatoric stress-axial strain besides volumetric strain-axial strain curves are predicted and compared with experimental data for verification.Results show fairly good performance of presented model.
