Flying swallow half-through arch bridge structure system and construction method
The invention relates to the technical field of bridge engineering, in particular to a flying swallow half-through arch bridge structure system and a construction method.According to the arch bridge structure system, main arch ribs and side arch ribs are fixedly connected through arch seats, the arch seats and main piers are restrained through supports, and particularly, at least two rows of fixed supports are arranged between the arch seat on one side and the main piers; according to the arch bridge structure system, a specific construction technology is adopted for constructing the bridge, the stress problem of the arch feet and the problem that the bearing reaction at the supports is not evenly distributed are solved, after the bridge is formed, horizontal displacement can be longitudinally released with the fixed supports as fulcrums, and the safety of the bridge is improved. All parts in the arch bridge structure system are in a self-balancing state, an overall upper structure formed by the main arch ribs, the side arch ribs and the main beams is supported on the main piers through the supports, and the upper structure does not generate any horizontal force on the lower structure.
本发明涉及桥梁工程技术领域，具体涉及一种飞燕中承式拱桥结构体系及施工方法，本发明中的拱桥结构体系通过将主拱肋和边拱肋通过拱座固结，拱座与主墩之间采用支座约束，具体在一侧拱座与主墩之间设置至少两排固定支座，在另一侧拱座与主墩之间设置至少两排活动支座，该拱桥结构体系采用特定施工工艺施工桥梁改善了拱脚受力问题以及支座处支反力分布不均的问题，成桥后，能够以固定支座为支点，纵向释放水平位移，上述拱桥结构体系中的各部分均处于自平衡状态，主拱肋、边拱肋和主梁形成的整体上部结构通过支座支承于主墩，上部结构对下部结构不产生任何水平力。
