Abstract: In this paper a yield surface of anisotropic and small-strain constitutive mo del(ASM)is presented based on energy equation and compared with yield surface of modified Cam-Clay Model ( MCC), yield surface from testing result . I t is clear that the new yield surface is closer to testing result than MCC . A function of distance between initial stress-strain point and point at state boundary surface is adopted to simulate stress-strain behaviour of soil in condition of small-strain. The new constitutive model is compiled into FEM program and calculation result is compared with experiment. It is show n that the model in this paper can better simulate main characteristics of soil than MCC

Key words: constitutive model , anisotropy , small-strain ;finite element
