摘　　要：根据爆炸相似律和水中冲击波的基本方程探讨了炮孔水耦合装药结构的孔壁压力;建立了爆炸载荷作用下岩石的动态应力场,据此从理论上求出了炮孔水耦合装药爆破时裂隙区半径、粉碎区半径和光面爆破或其它成型控制爆破的最佳装药不耦合系数;最后,通过工程实践进行验证。according to the similitude law of blast and the equations of shock wave in water , this paper searched the bore wall pressure of bore water coupling charge structure and established rocky dynamical stress field under the function of blasting load ,and then obtained the crack area radius , the pulverizing area radius and the best uncoupling coefficient of bore water coupling charge in theory. Finally, it was examined and certified by engineering practice.
