The invention relates to ultra-high-performance steel fiber reinforced concrete, which is prepared from cement, silica fume, standard sand or river sand, a water reducing agent, water and copper-coated steel fibers. A preparation method of the ultra-high-performance steel fiber reinforced concrete comprises the steps of adding the cement, the standard sand or river sand, the silica fume and a component B of the water reducing agent into a forced mixer, and evenly mixing to prepare a dry material; adding half of a component A of the water reducing agent and the water into the dry material, and evenly mixing; adding the rest half of the component A of the water reducing agent and the water into the dry material, and evenly stirring; adding the steel fibers for 3-5 times, and continuously stirring until the steel fibers are evenly distributed. Tests prove that test pieces prepared from the ultra-high-performance steel fiber reinforced concrete have the compressive strength exceeding 150MPa and the ultimate tensile strength exceeding 6MPa, have good flowability and are easy to maintain. The ultra-high-performance steel fiber reinforced concrete is suitable for lower structures of reinforced concrete bridges, steel-concrete composite structure bridges and the like as well as lower structures of piers and abutments of the bridges.
