Experimental Study on Damage Properties of Rocks Under Dynamic Loading

Gao Wenxue; Hu Jiangbi; Liu Yuntong; Feng Bi; Sun Guofu (College of Architecture and Civil Engineering, Beijing Polytechnic University, Beijing 100022 )  
The shock-induced experiments for two typical rocks are done using the planar impact technique on the one-stage light gas gun, and the ultrasonic tests on the damaged rocks have been measured by use of the' ultrasonic pluse-transmission method. The shock-induced damage of rocks are related with the shock speed and the attenuation coefficient. The attenuation coefficient can be used as main damage parameter for constructing the damage of rocks under dynamic loading.
