摘要

Aimed at the notable non-ideal characteristic of aluminiferous explosive, theapplicability of shock similarity law in an underwater explosion far-fieldwas experimentally explored. Underwater explosion tests were conducted ina blast pond withstanding the explosion of an 8-kg-TNT equivalent charge.The pressure-time curves were measured at different distances from theexplosion center. And the peak pressure and the pressure attenuation timeconstant were obtained. Combined with the dimensional analysis and thecharacteristic of aluminiferous explosive, the applicability of the shocksimilarity laws was discussed. Experimental results show that the peakpressure follows obviously a similarity law, but the time constant cannot do.It is related with the energy release from the secondary reaction betweenaluminum powders and oxidant.
