Reinforced concrete continuous rigid frame arch bridge and construction method thereof
The invention discloses a reinforced concrete continuous rigid frame arch bridge and a construction method of the reinforced concrete continuous rigid frame arch bridge. The reinforced concrete continuous rigid frame arch bridge comprises bridge abutments located at two sides and a main beam enabling the bridge abutments at the two sides to be connected, wherein bridge piers are arranged at the bottom of the main beam, the bridge abutments, the main beam and the bridge piers are all in rigid connection, the lower portion of the cross section of the main beam is of a structure of a continuous arch slab (5) or a continuous arch box (10), and a continuous pi-shaped structure in rigid connection with the continuous arch slab and the continuous arch box is arranged above the continuous arch slab and the continuous arch box; the continuous arch slab and the continuous arch box comprise a middle span (3) and side spans (4), the two ends of the middle span (3) are in rigid connection with the bridge piers, one end of each side span (4) is in rigid connection with the corresponding bridge pier, the other end of each side span (4) is in rigid connection with the corresponding bridge abutment, and an overall structure in rigid connection exists between the middle span and the side spans. The reinforced concrete continuous rigid frame arch bridge and the construction method of the reinforced concrete continuous rigid frame arch bridge organically combines an existing prestressed concrete continuous rigid frame bridge and a reinforced concrete arch bridge, well solves the technical problem that in later-period operation of the existing prestressed concrete continuous rigid frame bridge, sinkage of the main beam is large and construction cost of the reinforced concrete arch bridge is high, and can improve the spanning capacity of a bridge girder.
