Comparison between Feature of Modified Cam-Clay Model and UH Model

摘要

Based on researching the features of the modified Cam-clay model and UH model,the mechanism of models modeling the behaviors of the overconsolidated (OC) clays can be revealed.For the OC clays,the curves predicted by the modified Cam-clay model have abrupt changing points,so the model cannot model continue and gradual changing process well.UH model can rationally model many characteristics of the OC clays well,including shear dilatancy,strainhardening and softening,and stress path dependence behavior.
