摘　　要：岩石既具有力学特性,也具有声学特性,两者之间存在密切联系。通过岩石声波测试,分析并建立了岩石波形衰减系数与动弹性模量之间的定量关系。结果表明:岩石波形衰减系数随岩石的动弹性模量的增大而减小,两者具有很好的幂指数关系,可以很好地验证定量关系的可靠性。研究结果对丰富现有的岩石力学参数获取方法具有重要意义。Rock has both mechanical and acoustic properties, which are closely related. The quantitative relationship between wave attenuation coefficient and dynamic elastic modulus of rock is analyzed and established by rock acoustic wave test. The results show that the attenuation coefficient of rock waveform decreases with the increase of rock dynamic elastic modulus, and the two have a good power exponential relationship. The test results can well verify the reliability of the quantitative relationship. The research results are of great significance to enrich the existing methods to obtain rock mechanical parameters.
