[0002] The bridge includes the upper structure and the lower structure. Due to temperature changes and concrete shrinkage and creep, the upper structure of the bridge will undergo expansion and deformation along the extension direction of the beam body. At present, the conventional structure system of the bridge generally adopts a simple support or a simple support first and then a continuous structure. The structural system is equipped with a large number of expansion joints to adapt to this expansion and deformation. In order to reduce the risk of bridge damage, since the expansion of the bridge needs to be smaller than the expansion of the expansion joints, considering the impact of expansion and deformation on the bridge, the bridge is divided by expansion joints , in order to ensure the traffic safety of the bridge, the joint length of the conventional structural system of the bridge is limited

The invention provides an integral seamless long connection structure of a bridge, and belongs to the technical field of bridge engineering. The integral seamless long connection structure of the bridge comprises a beam body, two side piers and a plurality of supporting structures, the two side piers are supported at the two ends of the beam body respectively, and the supporting structures are arranged between the two side piers at intervals in the extending direction of the beam body and comprise two first supporting structures, two second supporting structures and third supporting structures. The two first supporting structures are located between the two side piers and are arranged adjacent to the two side piers respectively, the two second supporting structures are located between the two first supporting structures and are arranged adjacent to the two first supporting structures respectively, and the third supporting structures are located between the two second supporting structures. The rigidity of the pier column of the first supporting structures, the rigidity of the pier column of the second supporting structures and the rigidity of the pier column of the third supporting structures are sequentially increased. The integral seamless long connection structure of the bridge can break through the connection limitation of the conventional structure system of the bridge.
Description
technical field [0001] The present application relates to the technical field of bridge engineering, in particular, to an integral seamless long-connected bridge structure. Background technique [0002] The bridge includes the upper structure and the lower structure. Due to temperature changes and concrete shrinkage and creep, the upper structure of the bridge will undergo expansion and deformation along the extension direction of the beam body. At present, the conventional structure system of the bridge generally adopts a simple support or a simple support first and then a continuous structure. The structural system is equipped with a large number of expansion joints to adapt to this expansion and deformation. In order to reduce the risk of bridge damage, since the expansion of the bridge needs to be smaller than the expansion of the expansion joints, considering the impact of expansion and deformation on the bridge, the bridge is divided by expansion joints , in order to e...
