When a ship explodes, it will cause serious damage to cabin equipment and shipboard personnel. It is one of the effective measures for shock wave protection to arrange water media in the closed cabin to form a water body. In order to analyse the attenuation effect of water medium on explosion shock wave, a model of shock wave propagation in a cabin with water body is established, and Euler method is used to describe the deformation and fragmentation of water body under the action of explosion shock wave. The calculation results show that water medium can effectively reduce the overpressure peak and quasi-static pressure of explosion shock wave, and the reduction effect increases with the increase of water thickness.
