| 摘 要： | 引入损伤来评估炸药爆炸动作用对岩石作用后果，建立了爆炸动作用对岩石损伤作用的半解析算法，并引入了有效应力强度因子的概念。在此基础上，对岩石爆破过程进行动静作用的耦合分析。分析的结果较为深刻地接示了破岩过程的力学机理。

| Abstract: | In this paper damage is employed to evaluate the blast ing dynamic effect and a semi-analytic calculation method about the damage on rock due to blasting dynamic effect is developed,and the coneept of effective stress intensity facfor is introduced as well.On this basis the authors carry out coupled analysis of dynamic-sfafic effect on rock blasting.The resulting conclusion reveals the mechanism of rock blasting |
