The invention relates to a long-span steel corrugated plate arch bridge. The arch bridge includes a main arch ring composed of U-shaped steel plates and steel corrugated plates, and the two ends of the main arch ring are fixed to a rebar concrete arch base through embedded parts; filling earth is arranged on the main arch ring, the surface of the filling earth is a bridge surface, and steel corrugated pipe ventral holes are formed in the filling earth arranged on the main arch ring. The steel corrugated plate arch bridge with ventral holes can feasibly improve the stress requirement of the steel corrugated plate arch bridge, has the advantages of being light, high in strength, good in flexibility, low in cost and the like, is an excellent substitute of a rebar concrete arch bridge, can be widely applied in the engineering of medium-sized bridges (30-60m), has good social benefits and plays an exemplary role in the development of modern bridges.
