The invention discloses a steel-concrete combined continuous beam bridge for releasing pulling stress of a carriageway slab. The steel-concrete combined continuous beam bridge comprises a steel beam and the concrete bridge carriageway slab fixed on the steel beam. A transverse penetrating breaking joint is formed in the position, above an intermediate pier corresponding to the continuous beam bridge, of the concrete bridge carriageway slab. The local sections of the two sides of the transverse penetrating breaking joint have relative longitudinal telescoping deformation between the concrete bridge carriageway slab and the steel beam. The pulling stress generated from high negative bending moment is unloaded and transferred to the steel beam, pulling of the concrete bridge carriageway slab is avoided, the stressing state of the whole steel-concrete combined beam is optimized, performance superiority of steel materials and concrete can be played, vertical load of the carriageway slab is directly transmitted to the steel beam, it is ensured that the carriageway slab does not generate abnormal vertical deformation, stress concentration and fatigue problems of the carriageway slab and the steel beam from fixing to separating in a junction connecting local area, construction and a construction technology of the carriageway slab are greatly simplified, and the whole stress performance of the bridge is improved, the using period of the beam bridge is prolonged, and the construction and maintaining cost are reduced.
