Abstract
To clarify the shock wave interface effect in shallow water explosion conditions, the theoretical and experimental research progress of shock wave linear reflection and nonlinear reflection is summarized from free water surface, underwater and the dual action of free water surface and underwater, respectively. The damage to concrete barrier and ship in shallow water is summarized, and the non-uniform shock waves distribution in the near field caused by the interface action and the variations in charge and detonation mode is analyzed. By regulating the explosive energy to change the energy output in a particular direction, it is feasible to improve the damage effect of shallow water explosion. It is noted that the development of the shallow water explosion theory is imperfect, and the near-field energy structure control, concrete target dynamic response and damage effect, and reflected shock wave-bubble interaction are vital research directions. 129 references are attached.
