摘　　要：内爆炸对坑道内的人员、装备、结构都具有巨大的毁伤效应,内爆炸的防护技术已成为研究的热点。本文就炸药在坑道内爆炸情况下水的消波效应,开展了坑道模型爆炸试验、实际坑道爆炸试验、数值模拟研究,结果表明:坑道内爆炸条件下水具有显著的消波效应。文中还给出了不同置水工况下坑道空气冲击波超压的衰减率范围,并对水消波效应的机理进行了初步探讨。Internal detonation can do great harms to the persons,equipments and structures in the tunnel,so the internal detonation damage effect protection technology becomes a hot issue to domestic and international researchers.In this paper experimental investigation and numerical simulation are carried out on the shock wave attenuation effect of water under internal detonation loading.Results obtained indicate that the shock wave attenuation capability of water is remarkable.The overpressure attenuation rates of water under different experiment situations are raised and the mechanism of shock wave attenuation effect of water is discussed preliminarily at the same time.
