Non-prestressed continuous integral box girder structure based on high-tensile concrete

The utility model discloses a non-prestressed continuous integral box girder structure based on high-tensile concrete, which belongs to the technical field of bridge engineering and comprises two prestressed reinforced concrete simply supported beams, a continuous concrete section and a high-tensile concrete section, the two prestressed reinforced concrete simply supported beams are longitudinally arranged at intervals, and the continuous concrete section and the high-tensile concrete section are arranged between the two prestressed reinforced concrete simply supported beams. And the high-tensile concrete section is poured above the continuous concrete section. According to the device, the high-tensile-strength concrete with the long length is arranged in the connected hogging moment area, the tensile strength is high, the ductility is large, the hogging moment of the pier top can be effectively counteracted, and therefore the problem that due to the fact that common concrete is adopted, the hogging moment ar
