中文摘要：
在50kPa、100kPa和200kPa3种固结压力下分别对饱和度为95％、92％、88％和83％的土样进行了循环单剪试验，得到了该土样存4种饱和度、3种固结压力下的最大动剪模量Gdmax以及动剪模量比G／Gdmax-γ归一化曲线。分析得出，同一固结压力下土样的Gdmax和G／Gdmax随着饱和度的增大相对减小；随着固结压力的增大，两者数值上差异逐渐减小。最后对此种现象进行了讨论并分析了其产生的原因。
英文摘要：
The cyclic simple shear tests of the saturated soil with saturation 95 % ,92% ,88% and 83 % were carried out under the consolidation pressure of 50 kPa, 100 kPa and 200 kPa, respectively. Of four sorts of soil sample under three consolidation pressures, the maximum dynamic shear modulus Gdmax and the dynamic modulus ratio G/Gdmax-γ generalized curves were attained and analyzed comparatively. The results show that under the same consolidation pressure, the values of Gdmax G/Gdmax shrink according to the growth of saturation ; with the increasing of the consolidation pressure, the differences among Gdmax and G/Gdmax-y decrease gradually. In the last part of the paper, this kind of phenomenon and its causes are under discussion and analysis.
