摘要
利用动三轴试验，研究了团结应力、固结比对软粘土弱化动力参数变化的影响．结果表明，若引入振动应力比与初始剪应力比参数，可以用归一化的等价线性关系描述软粘土的弱化动力性质，从而为其动力参数的测试及应用提供一种更为合理的方法．
The effects of the consolidation stress and the consolidation ratio on the cyclic degradation parameters is studied by using cyclic triaxial tests of soft clay. The results show that cyclic degradation behaviour of soft clays is described by the normalized equivalent linear relation if the cyclic stress ratio and initial shear stress ratio are defined.Thereby the reasonable method is developed for measuring and applying cyclic parameters of soft clay.
