摘　　要：探讨了炮孔和装药间以水不耦合介质爆破时,在爆轰波压力和高压、高温爆生气体压力作用下,水中爆炸冲击波的形成和传播规律,求解了冲击波的初始参数和孔壁处冲击波参数,并应用弹性波动理论,提出了正入射情况下岩石内的初始冲击压力。The formation and propagation of blasting shock wave under the compressing action of explosion shock wave and high-temperature high-pressure explosion gas products in water-uncoupling, and calculates preliminary parameters of shock wave and parameters of shock wave in the position of hole wall are discussed in this paper. Based on the elastic theory and fluctuating theory, the preliminary shock pressure on the rock of hole wall in case of normal incidence is put forward.
