Tension face layer compound-reinforced reinforced concrete continuous rigid frame bridge and construction method thereof
The invention discloses a tension face layer compound-reinforced reinforced concrete continuous rigid frame bridge and a construction method thereof. The continuous rigid frame bridge comprises a bridge pier, an abutment, a reinforced concrete girder and a bridge floor. The pier top hogging moment section of the girder is of a box-shaped section beam structure, a sagging moment section of the girder is of an n-shaped section beam structure, the bottom surface of a sagging moment section beam rib is provided with a steel plate reinforcement layer fixedly connected to a stirrup, and the girder is formed by pouring composite concrete evenly doped with a flexible material. The tension face layer compound-reinforced reinforced concrete continuous rigid frame bridge is simple to construct and clear in stress, can meet the requirements of crack resistance and crack stopping needed for durability of the concrete bridge, and is suitable for being applied to bent, sloping and inclined concrete continuous rigid frame bridges of medium and small spans where concrete tension and cracking cannot be overcome by pre-stressed strand arrangement easily.
