摘　　要：根据波的界面透射和反射理论,分析了爆炸能量的传递规律,探讨了不同装药结构(耦合装药、空气不耦合装药、水不耦合装药)对爆炸能量传递的影响,并建立了上述三种装药条件下传递给岩石的爆炸能量计算公式。通过分析表明炸药与岩石的波阻抗、装药不耦合系数以及不耦合介质的可压缩程度是影响爆炸能量传递的主要因素。Based on the theory of the transmission of reflected wave and retracted wave at interface, the transmission of explosion energy is analyzed and the influence of different kinds of charging structure (coupling charge, decoupling charge with air and decoupling charge with water) on explosion energy transmission is discussed in this paper. In addition, the formulas for calculating explosion energy transmitted to rock are built under the conditions of the different charges mentioned above. According to the analysis, wave impedance between rock and explosive, decoupling charge coefficient and the compress degree of decoupling material are the main factors of explosion energy transmission.
