Arch bridge structure and construction method thereof
The invention discloses an arch bridge structure and a construction method thereof, the arch bridge structure comprises two groups of arch ribs, each group of arch ribs comprises a main arch rib and side arch ribs on two sides of the main arch rib, the main arch ribs are fixedly connected with main piers on two sides, the side arch ribs are fixedly connected with the main piers and auxiliary pier cross beams, and the arch bridge structure further comprises a first cross beam located below a bridge floor and connected with the two main arch ribs; the two ends of the center hole longitudinal beam are supported on the first cross beams on the two sides respectively; the inner side end of the side hole longitudinal beam is fixedly connected with the first cross beam; the auxiliary hole longitudinal beam is fixedly connected with the outer side end of the side hole longitudinal beam, and a triangular rigid frame system is formed between the side hole longitudinal beam and the main arch rib and between the side hole longitudinal beam and the side arch rib, so that the earthquake force of each key control position of the arch bridge is reduced, and the arch bridge adapts to the geological conditions that the rigidity is weak and thrust cannot be provided.
本发明公开了一种拱桥结构及其施工方法，包括两组拱肋，其中每组该拱肋包括主拱拱肋和其两侧的边拱拱肋，该主拱拱肋固定连接两侧主墩，该边拱拱肋固定连接该主墩和辅助墩横梁，还包括：第一横梁，位于桥面以下，连接两个主拱拱肋；中孔纵梁，两端分别支撑在两侧的该第一横梁上；边孔纵梁，内侧端与该第一横梁固定连接；辅助孔纵梁，与该边孔纵梁的外侧端固定连接，通过形成边孔纵梁与主拱拱肋和边拱拱肋之间的三角刚架体系，从而降低拱桥各关键控制位置的地震力，并适应刚度较弱、不能提供推力的地质条件。
