%X Dynamic damage of brittle rocks is an evolution process of inconvertible energy dissipation. The damage dissipation energy can be calculated through the area between Rayleigh line and Hugoniot shock adiabatic curve. The shock-induced damage experiments are carried out by means of a gas gun. The stress wave curves are measured using the planar impact techniques. Based on the experiment results and the Rankine-Hugoniot conservation equations,the damage energy dissipation of brittle rock under impact loading is calculated. The rock damage evolution rules are fairly delineated,which contribute to establish the new rock damage model.
