摘要：

Based on the theory of field of plastic moduli and the multi-yield-surface constitutive model, and combined with isotropic hardening rule and translating hardening rule, a new multi -surface elastoplastic constitutive model was proposed in a new stress space. And a simple model which was suited to the triaxial tests, was infered. Finally, combined with a residual pore-water pressure model, the new model has been validated by means of a cyclic triaxial test of saturated soft clay. The validation indicates that the multi-yield-surface constitutive model can be used to simulate the cyclic triaxial test, direct shear test and plane strain test.
