The invention discloses a marine anti-fatigue sectional material through hole structure which comprises a through hole body formed in a mother board, and a sectional material is arranged in the through hole body in a penetrating mode. The stress dispersion hole and the through hole body are integrally formed, the stress dispersion hole is located in the side, close to the top of the sectional material, of the through hole body, the stress dispersion hole comprises a linear part and a buffering arc part, one side of the linear part makes contact with the side wall of the sectional material, and the other side of the linear part makes contact with the side wall of the sectional material. And the other side of the direct part is connected with the top hole edge of the through hole body through the buffer arc part. No high stress concentration point exists, and the risk of fatigue damage of the through hole body is reduced. And the device also has the advantages of reasonable design, simple structure, high efficiency, low cost and the like.
