| 摘 要： | 基于现有岩石爆破机理和岩石细观损伤力学 ,认为岩石爆破损伤断裂过程包含有爆炸应力波的初期动态损伤演化阶段和后期爆生气体作用下的准静态损伤演化阶段 ,并分别建立了这两个阶段的损伤模型和断裂准则 ,阐述了岩石爆破损伤断裂的细观理论。

| Abstract: | Based on existing rock blasting mechanism and rock meso damage mechanism,the precess of rock blasting damage is presented,which includes both the initial dynamic involution stage during the stress wave and the final static stage during detonation gases.The damage models and the fracture criterion of these two stages are established individually.The theory of damage and the meso mechanism of fracture on rock blasting is analyzed. |

| Keywords: | rock blasting explosive stress wave detonation gases damage mechanism |
