摘要

In order to investigate the shape and evolution process of water column caused by a near surface explosion in deep water situation, underwater explosion experiments with 1 kg of RDX charge at different detonation depths are carried out using a high-speed camera. The evolution characteristics and parameters of water columns including the height, width and prominent time are obtained and compared with those published by Cole, Hole and Swisdak et al. The results show that vertical ejection is the main shape of water column, and a few additional radial ejections occur when the bubble reaches the free surface at its expanding phase. The maximum height of water column fluctuates with the explosion depth, while the width of water column decreases linearly. Empirical formula of water column height by Swisdak is not suitable to near surface underwater explosion in deep water situation.
