一种地下弹仓，它有一个炸药储藏室、一个水平通道和一个用于排气的竖井。它是在日本提出并立法的。作者发现，储藏室地板上的少量水显著缓解了爆炸压力。其缓解机制已有研究，但仍不十分清楚。为了研究水对爆炸波的抑制作用，进行了透明正方形直管内爆炸试验。管子中的水的排列和数量有五种不同的方式。通过测量管内和管外的爆炸压力，评价了缓解效果与水的布置和水量的关系。研究结果表明，水对爆炸波的抑制主要是由于爆炸与爆炸点附近的水的相互作用所致。相反，管的其他部分的水被发现增强了爆炸压力。
A subsurface magazine has an explosive storage chamber, a horizontal passageway, and a vertical shaft for vent. It was proposed and legislated in Japan. The authors found that small amount of water on the floor of its storage chamber mitigated the blast pressure remarkably. The mechanism of the mitigation has been studied, however, it is not still well understood. In this study, the explosion in a transparent, square cross section, and straight tube was carried out to examine the mechanism of blast-wave mitigation by water. The arrangement and amount of water in the tube were varied for five ways. The dependence of mitigation effect on the arrangement and amount of water was evaluated by measuring the blast pressures in the tube and outside the tube. The results of this study concluded that the mitigation of blast wave by water is mainly due to the interaction between the explosion and the water very near the explosion point. On the contrary, the water at other part of the tube was found to strengthen the blast pressure.
