摘　　要：为研究震动波在浅层地质条件中的传播特性,依据震动波的振幅和频率衰减吸收特性,分别以Maxwell、Kelvin-Voigt和标准线性黏弹性介质为震动波传播介质,建立了这3种介质震动波的传播特性模型。通过实验,计算比较3种模型预测波形与实测波形的相似系数,验证了建立的3种模型的描述效果可以用来描述浅层震动波传播特性,其中Kelvin模型的描述效果最好。In order to study the propagation characteristics of shock waves in shallow geological conditions,according to the amplitude and frequency attenuation characteristics of the shock wave,Maxwell,Kelvin-Voigt and standard linear viscoelastic media were used as the vibration wave propagation medium.And the propagation characteristics of the vibration wave in these three media were established.Through experiments,the similarity coefficients between the predicted and measured waveforms of the three models were calculated and compared.It is verified that the descriptive effect of the three established models can be used to describe the propagation characteristics of shallow vibration waves,and the Kelvin model has the best description effect.
