Abstract: The underwater explosion is one of the major threats to the warships in the sea battle field.In order to provide accurate loads input for the study of warship explosion protection,a systematic study on the loads is d esired.By reviewing numerous literature both at home and abroad,researches on under water explosive load in the field of warship anti-explosion were summarized,especially the research advances on the loads by the shock wave and the air bubble.The research on the loads by shock wave is relatively mature,therefore,much more efforts must be made on the investigation and analysis on the air bubble motion equation and fluid jets from the bubble.Based on the previous work in the area,some of the problems to be solved are raised and advancements are predicted,which can provid reference for the study in this area.
