Aiming at the influence caused by rusting of arch rib of concrete - filled steel tube arch bridge on structure durability, reasons of causing rusting of arch rib and different requirements of arch rib of each bridge on rust protection are analyzed, new methods and process on arch rib protection of steel tube arch bridge at home and abroad at current stage are introduced, and merits and demerits of all kinds of protection processes are analyzed. Taking the disease of corrosion prevention system of arch rib of steel tube arch bridge in a coastal area as an exam- ple, special treatment methods are proposed according to specific conditions, providing basis for corrosion preven- tion and rust protection construction of arch rib of steel tube arch bridge.
