The invention discloses a steel-concrete combined section structure of a cross beam between ribs of a half-through arch bridge. The steel-concrete combined section structure comprises concrete arch ribs, pre-embedded steel plates, anchor plates, shear nails, pre-embedded steel bars, prestressed anchor bars, the cross beam between the ribs, anchor sealing concrete, anchor sealing steel bars and the like. The steel cross beams are adopted as the inter-rib cross beams, compared with traditional concrete cross beams, the weight of the cross beams is greatly reduced, and transportation and hoisting are more convenient; by arranging the prestressed anchoring ribs, the shear nails and the embedded steel bars, the shear resistance of the joint surface can be remarkably improved, and the stability of the connecting part is effectively enhanced; the prestressed anchoring ribs are finish-rolled twisted steel ribs, and compared with prestressed steel strands, the finish-rolled twisted steel ribs have ...
