| 摘 要： | 本文简要介绍突变理论的尖点突变模型。在分析层状岩体在爆炸冲击荷载作用下破碎程度主要受控因素的基础上,运用拟合的途径建立了岩石破碎分析的尖点突变控制方程。该方程可以被用来直接定量计算岩石破碎块度发生明显变化点的炸药单耗(q)或炮孔与层状结构面间的夹角(α),实践证明是可行的。

| Abstract: | Point model of catastrophic theory is introduced in this paper. Based on the analysis about control factors of layered rockmass under the action of blasting board, we use data from field blast test to build the control formula which can be used to predic that uncontinuous feature of rock fragmentation varying with the control factors a or g. This formula has been proved to be correct. |
