The invention discloses an anti-impact marine reactor cabin bottom structure which comprises an inner bottom plate and an outer bottom plate, and the inner bottom plate is used for being connected with the side wall of a reactor cabin to form a bottom pressure boundary of a reactor cabin containment; a plurality of rows of transverse perforated rib plates and a plurality of columns of side girders are arranged between the inner bottom plate and the outer bottom plate, and the plurality of rows of transverse perforated rib plates and the plurality of columns of side girders are arranged in a criss-cross manner to form a grating structure; a plurality of longitudinal reinforcing ribs parallel to the side girders are arranged among the side girders, and the longitudinal reinforcing ribs and the transverse perforated rib plates are arranged in a criss-cross mode. According to the anti-impact marine reactor cabin bottom structure, the inner bottom plate, the outer bottom plate, the side girders between the inner bottom plate and the outer bottom plate and the transverse perforated rib plates form a grid structure, and the structural strength and rigidity of the cabin structure under various loads are guaranteed.

    本发明公开了一种抗冲击船用反应堆舱底部结构,该结构包括内底板和外底板,所述内底板用于与堆舱侧壁连接,形成堆舱安全壳的底部压力边界;所述内底板与外底板之间设置有若干行横向开孔肋板和若干列旁桁材,若干行所述横向开孔肋板和若干列所述旁桁材纵横交错布置形成格栅结构;若干列所述旁桁材之间设置有若干个与其平行布置的纵向加强筋,所述纵向加强筋与横向开孔肋板纵横交错布置。本发明的抗冲击船用反应堆舱底部结构通过内底板、外底板和两者之间的旁桁材、横向开孔肋板形成格栅结构形成格栅结构,保证舱室结构在各类载荷下的结构强度和刚度。
