：This article analyzes constraint condition of Dandong port including large tidal range,high wharf surface,a vast variety of ship types,great difference of length and springboard angle.The springboard of automobile ro-ro ship can’t overlap the joint with the wharf surface,and can’t implement handling operation.So we must research design ideas and solutions for shore facilities of automobile ro-ro ship in area with large tidal range.The freeboard height of pontoon adapts to the ship draught variation,and the pitching of steel bridge adapts to the tidal variation,to adapt to the springboard height variation caused by the ship draught and tidal variation and thus realize smooth handling operation.
