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 dynamic damage evolution of brittle rock is discussed. Based on the experimental results, the dynamic damage evolution equation of rock is established by introducing the relationship between the energy dissipation rate of the damage and the sound attenuation coefficient. A new model is developed to describe the dynamic damage evolution of the rock. Theoretical model
