The utility model discloses a simply supported T-beam web variable cross-section reinforcing structure based on UHPC and high-strength steel bars, which comprises a U-shaped reinforcing layer arranged outside a T-beam web and embedded steel bars connected with the T-beam web and the U-shaped reinforcing layer, the U-shaped reinforcing layer comprises a steel reinforcement cage and ultra-high performance concrete poured outside the steel reinforcement cage, the U-shaped reinforcing layer is divided into three sections along the length direction, wherein the middle part is a mid-span section, two ends of the mid-span section are supporting sections, the cross section size of the mid-span section is unchanged, and the cross section size of the supporting sections is changed. The simply-supported T-beam web variable cross-section reinforcing structure based on the UHPC and the high-strength steel bars greatly improves the bending resistance and the shear resistance of a T-beam bridge, is excellent in anti-seepage
