| 摘 要： | 在配有软回收装置的平板碰撞实验台上进行两种典型岩石冲击损伤实验，并对回收样品进行超声波测试，得知岩石的动态损伤与冲击速度和超声波衰减系数有关，后者较好的反映了岩石的损伤程度。结果表明声波衰减系数可作为表征岩石损伤模型的主要参量。

| Abstract: | The shock-induced experiments for two typical rocks are done using planar impact technique on the one-stage light gas gun,and the ultrasonic tests in the damaged rocks have been measured by the use of the ultrasonic pulse-transmission method.The shock-induced damages of rock are related with the shock speed and the attenuation coefficient of sonic wave,and the latter reflects the damage degree in rock fairly authentic.The attenuation coefficient can be used as main damage parameter for constructing damage model of rock under dynamic loading. |

| Keywords: | rock damage dynamic loading attenuation coefficient |
