Half-through arch bridge and construction method thereof
The invention relates to the technical field of bridge construction, in particular to a half-through arch bridge and a construction method thereof.According to the half-through arch bridge, a main beam, a main arch rib and a side arch rib are consolidated into a whole, the main beam not only bears the load of a bridge floor, but also participates in overall stress of the structure, and external tie bars do not need to be additionally arranged for balancing the thrust of the arch ribs; the external tie bar is effectively prevented from being tensioned for multiple times in the construction process, the construction process is simplified, the construction period is shortened, and the project investment is greatly reduced; in addition, the half-through arch bridge structure also has good stress performance and also has enough vertical rigidity under the vertical live load action of the train, the corner at the end of the main beam is small, the requirement for ultrahigh-speed traveling can be met, and the safety and comfort of high-speed railway traveling are ensured.
本发明涉及桥梁施工技术领域，具体涉及一种中承式拱桥及其施工方法，其中中承式拱桥将主梁和主拱肋、边拱肋固结为整体，主梁不仅承担桥面荷载，还参与结构整体受力，无需额外设置体外系杆用于平衡拱肋推力，有效避免了施工过程中体外系杆多次张拉，简化了施工流程，节省施工工期，也大大减小了工程投资；而且该中承式拱桥结构形式也具有良好的受力性能，在列车竖向活载作用下同样具有足够的竖向刚度，主梁梁端转角小，也能够满足超高速度的行车要求，确保高速铁路行车的安全性及舒适性。
