中文摘要：

在100、200、300kPa三种固结压力下，分别进行了原状土样的循环单剪试验、扰动土样的动三轴试验。得到了最大动剪模量Gdmax和G／Gdmax-γ曲线，并进行了对比分析。结果表明：由循环单剪试验得到的原状土的最大动剪模量Gdmax比相同固结压力下的扰动土样的动三轴试验结果稍低，Gd／Gdmax-γ曲线也有一定差异，且随着固结压力的不同而变化。

英文摘要：

Cyclic simple shear tests on undisturbed samples and dynamic triaxial tests on compacted speciments were performed under 100, 200, and 300 kPa consolidation pre.ssures. The maximum dynamic shear modulus Gdmax and the curves of Gdl Gdmax-γ were obtained and analyzed comparatively. It was shown that the maximum dynamic shear modulus Gdmax obtained from cyclic simple shear test was less than that of dynamic triaxial test, and the relation of Gd/Gdmax - γ was different under different consolidation pressures.
