| 摘 要： | 对岩爆问题中块体的高速弹出机制进行探讨。从柔性加载和刚性加载角度定性地估算了飞出块体的速度；从受横向约束薄板的失稳角度对此进行机制解释，并对板的边界约束情况进行讨论；对失稳后块体能量进行分析，结果表明，此时块体速度可达10 m/s，而且岩体的抗拉强度同样影响块体速度大小

| Abstract: | Giving a discussion on the mechanism of high rock velocity in rockburst,the rock velocity is estimated from the perspective of flexible loading and rigid loading;then the mechanism of it is explained from the point of the buckling of transverse constrained plate,the constraining condition of plate is also discussed,the energy of destroyed rock is analyzed.The result shows that the velocity of rock may reach 10 m/s and the tensile strength of rock also influences the velocity. |

| Keywords: | rockburst buckling instability constraint velocity |
