| 摘 要： | 利用自由场试验研究了土中装药不同埋设深度爆炸问题,给出了相应的爆炸宏观特征,得到了耦合系数试验数据,得到的结论是:当土中装药比例爆炸埋深超过2.0m/kg1/3后,爆炸达到完全封闭。并指出该数据与美军设计规范TM5-855-1中的耦合系数数据0.56m/kg1/3相差较大,分析了产生差异的可能原因。

| Abstract: | Free-field experiments of explosion with different burial depths in soil are carried out, the macro characteristics of explosion are presented, and the coupling coefficient data are obtained. The conclusion is that the explosion is fully closed if the scaled burial depth in soil exceeds 2.0m/kg1/3. It is pointed out that much difference exists between the finding of the study and the coupling coefficient data 0.56m/kg1/3 in TM5-855-1 (Fundamentals of Protective Design for Conventional Weapons). The possible reasons are also discussed. |
