摘要
初步探讨了炮孔水压爆破时,水中冲击波的初始参数和孔壁处冲击波参数;应用弹性理论和波动理论推导出了孔壁岩面上的冲击压力。
When water-pressure blasting, initial shock wave parameters in water and shock wave parameters in hole walls are discussed in this paper. In addition, preliminary shock pressure of rock hole walls is calculated with elastic theory and fluctuating theory.
