Notes:
According to unified strength parameters obtained from unified strength theory, the slopeof critical state line is modified to reflect critical states of different geomaterials under general stressstates. Yield function that can consider the effect of the third deviatoricic invariant is proposed, andan elasto-plastic constitutive model is established by adopting non-associated flow rules;furthermore, methods of overcoming singular points on the yield surface are discussed. Theproposed model is verified by true triaxial tests of clay, and results show that the model can wellpredict stress-strain relationships
