| 摘 要： | 受大药量岩塞爆破时爆破强烈震动和强震时水压力、高速水流作用下的岩塞聚碴坑高边墙围岩稳定问题显得十分突出。在研究边墙围岩的软弱结构面的物理力学特征及其组合形式与边墙的交割关系的基础上，充分考虑皮震动荷载影响因素，选择滑体单位宽度，按视倾向下滑，应用岩体力学和工程力学的有关理论进行稳定分析计算和锚索锚固计算的研究方法，经运行实践证明是可行的。

| Abstract: | The stability of high sidewall of brocken rock accumulating pit for rock plug blasting is very serious since the intense vibration caused by blasting of large amount explosives, as well as the influences of water pressure and the high speed current. On the basis of studying the physical and mechanical features of weak discontinuties and their intersecting relationships, applying the theories of rock mechanics and engineering mechanics, the sability of unit width rockmass sliding along apparent dip direction and necessary rock bolts or cables for reinforcement had been carried out. Practical result proved that the analysis is successful. |
