本文对一粉质粘土,在100kPa、200kPa、300kPa 3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,得到了该粉质粘土2种土样、3种固结压力下的D/Ddmax-γ曲线.试验结果表明,由循环单剪试验得到的原状土的D/Ddmax-γ曲线与扰动土样的动三轴试验结果D/Ddmax-γ曲线有一定差异,且随着固结压力的不同而变化.
For silty clay, the cyclic simple shear test of undisturbed samples and the dynamic triaxial test of compacted speciments were performed under 100kPa,200kPa and 300kPa consolidation pressures and the curves of D/Ddmax-γ were obtained. Experimental results show that the relation of D/Ddmax-γ is different under different consolidation pressures.
