The invention relates to the technical field of box culvert structures, in particular to a UHPC steel bar box culvert structure and a prefabrication method thereof. The box culvert main body is mainly formed by pouring a cementing material, aggregate, filler, an additive, water and ultra-high performance concrete added with mixed fibers. The structural strength is improved by adjusting the water-binder ratio of concrete raw materials, the structural density is reduced by using pre-wetted shale ceramsite, hollow glass beads and other light materials in the concrete raw materials, and the tensile property of the structure is improved by optimizing the adding proportion of steel fibers and polypropylene fibers. In the prefabrication process, an overturning inner mold is adopted as a reinforcing steel bar binding platform, and high-temperature steam is used for concrete curing. Through the optimization, the high-strength characteristic of the concrete box culvert is ensured, meanwhile, the overall density and the wall thickness of the box culvert are effectively reduced, and the tensile capacity of the box culvert structure is remarkably improved.
