    Abstract
  • In order to study the load characteristics of underwater explosion for an emulsion explosive, underwater explosion experiments of the emulsion explosive were carried out. By changing critical parameters such as explosive charge mass, explosion distance and depth, the typical parameters of underwater explosion shock waves and bubble loads were obtained for different cases. The energy output was analyzed and compared with TNT for the calculation formula of underwater explosion loads, then the TNT equivalence for underwater explosion of the emulsion explosive was attained. The results show that Geers-Hunter formula can predict the general law of load output of underwater explosion for the emulsion explosive, especially with regard to the bubble pulsation period. The bubble oscillation pressure accounts for 10%–20% of the initial shock wave peak pressure, and the bubble energy is about twice the shock wave energy. The oscillation pressure waveform exhibits a trend of slowly rising to the peak, then rapidly falling to zero and keeping a steady state, thus the rising edge of the waveform generally takes longer time than the falling edge. The average TNT equivalence of the emulsion explosive in underwater explosion is about 0.595 as to the same shock wave overpressure, and about 0.646 as to the same bubble pulsation period. This research results can provide important reference for the application of emulsion explosives in underwater explosion.
