The invention relates to a steel-concrete combined box girder structure with a wave-shaped upper flange cross beam and a construction method. The steel-concrete combined box girder structure comprises a groove-shaped box girder, a concrete bridge deck and the wave-shaped upper flange cross beam. The groove-shaped box girder comprises a box girder bottom plate and box girder webs, the box girder webs are installed on the left side and the right side of the box girder bottom plate, and the box girder webs on the two sides above the bottom plate are arranged at intervals in the transverse direction or are not internally arranged. The upper ends of two adjacent box girder webs on the groove-shaped box girder are connected through a plurality of wave-shaped upper flange cross beams which are arranged at intervals in the longitudinal direction, and the upper ends of the wave-shaped upper flange cross beams are connected with a concrete bridge deck laid on the groove-shaped box girder through shearing force connecting pieces. The box girder structure is high in transverse rigidity; and transverse damage to the steel-concrete combined box girder bridge deck with the large span can be avoided, the bearing capacity of the box girder structure is improved, the thickness of the concrete bridge deck can be effectively reduced, the steel girder part has the enough height, and therefore the steel-concrete combined box girder has the enough bearing capacity.
本发明涉及一种带波形上翼缘横梁的钢混组合箱梁结构及施工方法，包括槽形箱梁、混凝土桥面板、波形上翼缘横梁；槽形箱梁包括箱梁底板、箱梁腹板，所述箱梁腹板安装在箱梁底板左右两侧，底板上方两侧的箱梁腹板之间沿横向间隔设置或不设置位于内部的箱梁腹板，槽形箱梁上相邻的两个箱梁腹板上端经沿纵向间隔设置的若干波形上翼缘横梁相连接，波形上翼缘横梁上端通过剪力连接件连接铺设在槽形箱梁上的混凝土桥面板，本箱梁结构横向刚度大，能够避免跨度较大的钢混组合箱梁桥面板横向破坏，提高箱梁结构承载能力，能够有效减小混凝土桥面板厚度，使钢梁部分有足够的高度从而保证钢混组合箱梁有足够的承载能力。
