In this paper,experiments and numerical simulation were conducted to study the damage effect of shaped charges exploding underwater on cabins near the shipboard,and discussed the propagation law of shock wave in multimedia structure and damage mechanism of the structure,providing reference to the design of protective structures. Results show that under the same explosive equivalent condition,explosives can only damage the first cabin of the cabins near the shipboard,the multi-media structure has a strong attenuation effect on shock wave,and the penetrator formed by shaped charge can cause perforation of front board and back board of the second cabin. The diameter of the hole is 1/3-1/2 of the charge. The enlargement of the liquid tank or the thickening of the liquid tank backboard can enhance the anti-explosion ability of the cabin near the shipboard.
