The water jet formed after the collapse of bubble in near-field underwater explosion can cause serious damage to local structure ship, and formation is asymmetric, which makes it difficult measure its data experiment. At present, studies on pressure time history curves are still relatively rare. In order study characteristics jet, test 2.5 g TNT explosive at bottom fixed ...

Abstract Emulsion explosive has been widely used in underwater blasting construction. To study the effect of perlite content on performance emulsion explosives under deep water conditions, with different applied pressures and contents was studied by using self-built explosion test system. The results show that, increase pressure water, energy as sensitizer a decreasing trend, which is consisten...
