| 摘 要： | 针对采用爆破施工时确定参数大多是靠工程经验，而没有进行机理分析问题；通过引入有效应力强度因子，从岩石断裂力学和爆生气准静态理论角度分析了岩石裂纹的启裂、止裂判据和扩展规律，为爆破参数的合理设计提供了理论依据。

| Abstract: | In view of the problem of the blast parameters determination,mostly only depending on the experience without blasting mechanism-analysis.The paper pulls in effective stress intensity factor,and rock fracture mechanics and the quasi-static theory of blasted gas are employed to derive the criterion of dehiscence and crack arrest,rule of crack extending,to supply the theoretical basic for reasonable design of blasting parameters. |

| Keywords: | blast loading extending of crack design of parameters |
