摘要
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.关键词
