摘　　要： 在不同固结压力下分别对原状粘性土样、扰动粉土样和砂样进行了共振柱和动单剪试验,用修正的Hardin-Drnevich模型对共振柱试验结果进行拟合,得出剪应变大于10-4时的剪切模量和阻尼,用此结果与振动单剪仪结果对比发现拟合较好。 This paper based on the experiment of resonance and single shear on undisturbed cohesive soil samples, disturbed silt and sand sampies under different consolidation pressures. The shear modulus and damping ratio were obtained through the modification of Hardin-Drnevich model from the results of resonance when shearing strain more than 10-4, and the results were titling the results of single shear very well.
