摘要
探讨了脆性岩石动态损伤演化规律；基于实验结果，通过引入损伤能量耗散率与声波衰减系数的关系，运用能量法则建立了岩石动态损伤演化方程；构造了一个反映岩石冲击压缩、拉伸损伤的理论模型。
The rock damage evolution rules are discussed. Based on experimental results, the relation between damage-dissipated energy and attenuation coefficient is given. And then, a damage-evolution relation based on the energy method and a damage model are established to connect the shock compression and tensile damage.
