| 摘 要： | 对原状黄土（ Ｑ４） 施加４ 种频率的等幅正弦波荷载进行动三轴试验，研究振动频率对原状黄土动本构关系的影响．结果表明，对应于４ 种频率的原状黄土的动本构关系均服从双曲线模型，但试验常数ａ 、ｂ 均随振动频率的增大而略有减小．讨论了试验常数、动弹性模量和阻尼比等随振动频率的变化规律

| Abstract: | Influence of vibration frequency on dynamic constitutive relationship of loess is studied under uniform sine loadings with 4 kinds of frequency.The results show dynamic constitutive relationship of loess for 4 kinds of frequency submits to hyperbolic equation.The test constant a and b decreases with increase of vibration frequency.The effects of vibration frequency on parameters of the hyperbolic equation,elastic modulus,shear modulus,damping ratio are discussed. |

| Keywords: | Vibration frequency Elastic modulus Dynamic triaxial test Loess Dynamic constitutive relationship |
