Abstract: Modified Cam-clay model in which the critical state concept is applied successfully,is the most important constitutive model to describe stress and strain relationship of soil mass,and it also is a foundation for developing a more advanced constitutive model.The projection of the modified Cam-clay model on plane is a circle,which does not agree with experimental observation of yield and failure traces of geomaterials on π plane.In three dimensional stress states,it is well known that Lade-Duncan...

Key words: yield critersion； critical state line； Cam-clay model； constitutive relationship； void water pressure；
