| 摘 要： | 以砂质混合粘土为例，通过实施不同初始固结比水平的动力循环荷载试验，考察了土的孔隙水压力和残余变形的发生过程。探讨了当将土的不等向固结分为初始剪应力和等向固结两种应力状态时，孔隙水压力和残余变形的预测方法。提出了归一化的孔隙水压力和累积损失能量及残余变形和有效应力比间的关系模型。

| Abstract: | Taking the sand clay as test material, the dynamic cyclic loading experiments for it with different initial consolidation levels are carried out, The history of pore water pressure and residual shear strain is studied. The prediction method of pore water pressure and residual shear strain is discussed, when the anisotropic consolidation is looked as two stress situations, i.e. initial shear stress and isotropic consolidation. And two unified models are established for the relationships between total energy dissipation and excess pore water pressure; and between residual shear strain and effective stress ratio. |
