地下杂志是日本一种新型的杂志，其定义是建造在地下并配备有其他运输工具升降机的杂志。与通常的隧道式地下杂志不同。
在模型地下弹药库中进行了炸药爆炸试验。并通过纹影摄影观察到从入口喷出的爆炸气体和冲击波。用压电传感器测量了冲击波超压。在地下弹药库中爆炸的这些外部影响被发现小于在地下弹药库中爆炸的外部影响。
利用PISCES 2DELK程序对上述现象进行了数值模拟。计算得到的气体和冲击波的最大超压和速度与实验值基本一致。
The subsurface magazine is a new type of magazine in Japan, which is defined as a magazine constructed underground and equipped with elevators of other transportation means. and is different from the usual tunnel type underground magazine.
Explosions of explosives in model subsurface magazines were carried out. and explosion gases and shock waves blown out from their entrances were observed by schlieren photography. The blast overpressures were also measured by piezoelectric transducers. these external effects by explosion of explosives in the subsurface magazines were found to be less than those in the underground magazines.
The above phenomena were simulated by numerical analysis using PISCES 2DELK code. Caluculated maximum overpressure and velocity of gases and shock waves were in fair agreement with their experimental values.
