摘　　要：采用应力波基础理论分析了耦合装药及不耦合装药在炮孔中的爆炸情况,得到了各种情况下装药产生的初始冲击压力的计算公式。对于空气不耦合装药提出了新的计算公式,并通过对比计算验证了它的可行性,分析了装药爆炸的初始能量传递效率,得到了影响初始压力和有效利用率的因素。Based on the stress-wave theory,the paper theoretically analyses each explosive situation of the coupling charge and decoupling charge,and so acquire the formulas of initial shock pressure which is produced by the different charging constitutions detonated in the hole.Especially to the air decoupling charge,it put forward a new formula which is verified its feasibility by comparative calculated.And transfer efficiency of the initial energy when charge explosion is also studied,the factors that affect the initial shock pressure and effctive utilization ratio are obtained.
