The invention relates to a concrete-filled steel tube arch bridge. The concrete-filled steel tube arch bridge includes side arch ribs, main arch ribs, suspension bars, tie bars and a bridge pier and abutment structure. Side span structures include side arch supports, side span cast-in-place reinforced concrete arch ribs, cast-in-place side arch end cross beams, side span cast-in-place cross beamsbetween ribs, cast-in-place side arch rib tie beams, cast-in-place side upright posts, flexible prestressed tie bars and cast-in-place bridge deck slabs. Mid-span structures include abutments, mid-span concreted-filled steel tube arch ribs, main arch hollow cross beams between ribs, precast hollow longitudinal beams, flexible prestressed tie beams, tie-bar steel plate boxes, truss-type permanent upper wind braces, K-shaped permanent intermediate wind braces, temporary wind braces, arch foot pre-embedded sections, inner steel strand whole-bundle-squeezed inhaul cable suspension bars and outer steel strand whole-bundle-squeezed inhaul cable suspension bars. The concrete-filled steel tube arch bridge has the beneficial effects that steel tube arch rib fixation brackets involved in the concrete-filled steel tube arch bridge can improve the stability during installation and construction of steel tube arch ribs, and the accuracy of butt joint can be guaranteed effectively.
