Abstract：The double bottom’s experiment model has been designed according to the surface ship’s bottom structure, meanwhile the working conditions has been set based on the impact factors of near-field and contact underwater explosion. Then the damage mode of the double bottom structure in near-field and contact underwater explosion will have been summarized through the analysis of experiments’ results, at the same time, the tensile fracture strain of double bottom models which are Q235 has been obtained by adopting the principle of equivalent volume for analyzing the crackle thickness in experimental models’ changes, which provides the reference data for ship’s anti-shock and anti-explosion’s theory and numerical research
