The utility model discloses a novel steel box and steel truss combined beam of a ballastless track of a high-speed railway, which comprises a steel box beam, a steel box beam extending gusset plate is arranged at the upper end of the steel box beam, the steel box beam extending gusset plate is two parallel vertical plates, the steel box beam extending gusset plate and the steel box beam enclose to form a mounting space, and the steel box beam extending gusset plate and the steel box beam enclose to form the mounting space. The lower connecting section of the steel truss is mounted in the mounting space, and the steel truss and the steel box girder extend out of the gusset plate and are fixed through a connecting structure. The requirement for laying ballastless tracks on a large-span simply-supported bridge of a high-speed railway is met through connection of the steel trusses and the steel box girders, the structural rigidity of the bridge is improved, the bridge deck tie beam end corner is reduced, and the
