The invention discloses an curved nuclear explosion resistance protective screen door which comprises two curved door leaves in a bi-parting mode, the upper part of the outer side surface of each doorleaf is connected with a wall body in a rotary mode through a wall connecting hinge, the lower part of the outer side surface of each door leaf is connected with the ground in a rotary mode through aground connecting hinge, door leaf driving motors are correspondingly installed on the wall body of the inner side of the two door leaves in a rotary mode, pushing seats are correspondingly arrangedon the two door leaves, the pushing seats are hinged to the tail ends of pushing rods of the door leaf driving motors, and the pushing rods are driven by the door leaf driving motors to push the doorleaves open or close the door leaves. According to the curved nuclear explosion resistance protective screen door, an elastic-plastic design theory is utilized, kinds of materials are adopted to formmain separating and load carrying members, and the air shock wave generated by a nuclear explosion is sufficiently absorbed and reduced; a high-alloy bulletproof steel material, high-intensity concrete and a high-effect neutron shielding material are adopted to composite in a multi-layered mode to form door bodies, and the gamma rays and the neutron flows radiated in the primary twenty seconds ofthe nuclear explosion are shielded effectively; and the utilization requirements of national defense and civil defense constructions which have comparatively high nuclear explosion protective degree requirements are met.
