The results show that the normalized relation among the cyclic modulus, the damping ratio, the accumulative deviatoric strain and the cyclic degradation parameter can be established if the cyclic stress ratio and initial shear stress ratio are used as normalized parameters. Thereby the reasonable method is supplied to measure and apply cyclic parameters of soft clay.展开更多
文摘The effect of the consolidation stress σc and the consolidation ratio kc on the cyclic degradation relation is studied by cyclic triaxial tests of soft clay. The results show that the normalized relation among the cyclic modulus, the damping ratio, the accumulative deviatoric strain and the cyclic degradation parameter can be established if the cyclic stress ratio and initial shear stress ratio are used as normalized parameters. Thereby the reasonable method is supplied to measure and apply cyclic parameters of soft clay.
