The invention discloses a bulwark structure at the abrupt change position of an outer plate. The bulwark structure comprises a bulwark plate arranged on the outer side of a bulwark outer plate on thelower portion of an upper-layer building. The bulwark plate is arranged on a top deck; the bulwark plate is rectangular; the top of the bulwark plate is flush with the upper deck of the top deck; thebottom of the bulwark plate is connected with a hull outer plate on the outer side of the top deck; a plurality of first vertical reinforcing ribs are fixedly arranged on the bulwark plate, and the first vertical reinforcing ribs are respectively aligned with the vertical main ribs positioned under the top deck; through holes are formed between every two adjacent first vertical reinforcing ribs inthe bulwark plate; second vertical reinforcing ribs are arranged between the through holes and the first vertical reinforcing ribs; transverse reinforcing ribs are arranged on the upper sides of thethrough holes; and the second vertical reinforcing ribs and the transverse reinforcing ribs are fixedly arranged on the bulwark plate. According to the invention, the stress distribution can be effectively improved, the stress concentration and cracks are reduced, and the plate thickness does not need to be greatly increased.
