arch bridge structure

Abstract

The invention provides an arch bridge structure. The arch bridge structure comprises multiple piers which are arranged in the width direction of a river channel at intervals. A bridge deck slab beam is arranged on the piers in an crossing mode, and arched structures are arranged in bridge holes formed by the piers and the bridge deck slab beam; each arched structure comprises two vertically-arranged side plates and an arched curved plate located under the two side plates, the side plates are arranged in the width direction of the river channel, the lower edges, facing the water surface, of the side plates are in an arched shape, the two arched sides of each arched curved plate are fixedly spliced with the arched lower edges of the two corresponding side plates. According to the arch bridge structure, a continuous porous arch bridge is formed, the number of the bridge holes can be flexibly regulated according to the requirements of the width of the river channel, the span of the bridge and the landscape, and the bridge is a beam-type bridge according to the stressing characteristic and is the arch bridge in appearance; accordingly, the arch bridge has the advantages, being relatively clear in stressing, easy and convenient to design and construct and low in requirement for a foundation, of the beam-type bridge and has the advantages, being attractive in appearance, of the arch bridge.

Description

technical field [0001] The invention relates to an arch bridge structure. Background technique [0002] A bridge is a building for roads, pedestrians, etc. to cross a river. There are mainly beam bridges, arch bridges, and cable bridges in the form of bridges. Among them, beam bridges and arch bridges are the most commonly used, and these two bridge structures have their own advantages and disadvantages. The advantages of beam bridges are that the force is relatively clear, the design calculation is simple, the construction technology is mature, and the design and construction have reached standardization. The disadvantage is that if the span is large, the beam section size is large and the appearance is not beautiful enough. The advantages of arch bridges are beautiful appearance and large bearing capacity potential. The disadvantages are that they require good foundation conditions (with large horizontal reaction forces), high stability requirements when the span is large...
