Liquid filled double bottom structure is a usual type for large surface vessel, so the optimal design of which has important significance for viability of vessels in war. Appling a FEM process of MSC.Dytan, and changing the depth of liquid cabins, the thickness of bottoms and the thickness of stiffening, the response of different double bottom structures to underwater explosion were studied. After comparing and analyzing the deformation, the optimal design method of double bottom structures filled with liquid resisting underwater explosion was achieved. The best depth of water in water cabins is 90%, the best ratio of thickness of inner bottom and outer bottom is 11/9, and the stiffening should be thicker than outer bottom and thinner than inner bottom.
