The explosion shock wave speeding characteristics in different media are compared, and the dynamic responses of the reinforced concrete slab in a typical air explosion and an underwater explosion are investigated. Furthermore, the dynamic response of the air and underwater explosive loads is analyzed in the cases with different amounts of explosive and at different initiation distances. It is shown that the explosion shock wave propagation is faster in the air than in the water; and the shock wave pressure is more quickly attenuated in the water. But the pressure peak of the shock wave in the water is larger than in the air. An underwater explosion may cause a significant damage to the concrete slab. The dynamic response of a concrete slab subjected to an underwater explosion is significantly higher than that for an air blast with the same mass of charge, both on the surface and on the back of blasting., authors=KONG Xiangqing, ZHAO Qian, QU Yandong, ZHANG Wenjiao, authorsList=KONG Xiangqing, ZHAO Qian, QU Yandong, ZHANG Wenjiao, authorCompany=Department of Civil & Architectural

articleAbstract=利用有限元软件ANSYS/LS-DYNA建立钢筋混凝土板在不同介质中（空中和水下）爆炸的数值模型，在对比分析爆炸冲击波在空中和水下传播特性的基础上，研究了空中和水下爆炸冲击波对钢筋混凝土板动态响应及损伤程度的影响，并对比分析了不同炸药量及起爆距离对钢筋混凝土板在空中和水下爆炸时动态响应的影响规律。研究表明，在近爆区域内，爆炸冲击波在空中和水下的传播特性存在较大的差异：在空中的传播速度较水下快，并且冲击波压力在空中衰减较水下快；但水下爆炸冲击波压力峰值较空中爆炸大很多，对钢筋混凝土板的潜在破坏能力较强。两种介质中爆炸时钢筋混凝土板的破坏形态对比分析，发现无论是迎爆面还是背爆面，同等炸药量及起爆距离下水下爆炸时混凝土板损伤程度均较空中爆炸时大。,
