Concrete beam-corrugated steel web beam combined continuous beam bridge
The invention discloses a concrete beam-corrugated steel web beam combined continuous beam bridge which comprises a concrete box beam segment arranged on bridge piers and a corrugated steel web box beam segment fixedly connected with the concrete box seam segment. The length of the corrugated steel web box beam segment is 1/4 to 1/3 of the span length of a bridge body. According to the concrete beam-corrugated steel web beam combined continuous beam bridge, the manner that a concrete box beam is combined with a corrugated steel web box beam is adopted, the heavy concrete box beam segment with larger dead load is arranged on the bridge piers below the bridge body, and the light corrugated steel web box beam segment with smaller dead load is located on the midspan segment of the bridge body; through longitudinal mixing, the defects existing in single systems of the concrete beam or the corrugated steel web beam are overcome, the integral rigidity of the beam bridge is guaranteed, and the situation that the midspan segment continuously warps downwards and cracks due to increase of the span of the beam bridge is avoided; and meanwhile, the concrete beam-corrugated steel web beam combined continuous beam bridge has the beneficial effects of being reliable in structure, easy and convenient to construct and good in economical efficiency.
