  5. The research indicate that the structured soft clay has below several characteristic, the viscous strain is produced during the stage of primary consolidation and of second consolidation, and in the prophase, the relation of stress - strain - strain rate is unique, so the form of constitutive model, such as, f ( v ', e ) = 0, f ( ' v, e, t ) = 0, ca n ' t describe strain behavior of soil skeleton rationally ; the time - dependent properties involve three aspects, in addition the time - dependent strain, apparent preconsolidation pressures that depend on strain rate, and the effect of creep compression on apparent preconsolidation pressures ; because of holding structural strength, the mechanics characteristic is determined by the magnitude of stress, and the compression curve is composed of several sections. by combining structural yield stress and it ' s characteristics with the improved time line model, a new one - dimensional elastic visco - plastic consolidation model is established
