Large-span concrete-filled steel tube arch bridge structure capable of improving wind resistance and construction method of large-span concrete-filled steel tube arch bridge structure
The invention provides a large-span concrete-filled steel tube arch bridge structure capable of improving wind resistance and a construction method of the large-span concrete-filled steel tube arch bridge structure, and belongs to the technical field of large-span arch bridges. In order to solve the problems that an existing arch bridge single-use wind-resistant cable is poor in effect compared with a wind-resistant cable and a damper; and the wind-resistant effect of the large-span arch bridge in the maximum single-cantilever construction state is poor. And the mechanical strength is low. The arch rib is a steel arch rib with two limbs distributed in parallel, the section of the arch rib truss chord member is of a box-shaped structure, and the arch rib is connected with the pier through a plurality of wind-resistant cables. The wind resistance of the large-span arch bridge can be ensured under the condition that the cost is reduced; the wind-resistant cable fixing device is simple in structure, wide in applicable working condition and universal on the water surface or the ground, compared with the situation that a wind-resistant cable needs to be fixed to the ground near an arch bridge, the construction difficulty can be lowered, the construction period can be shortened, the situation that the wind-resistant cable is not easy to fix when the arch bridge is on the water surface is avoided, and self-body wind-resistant cable fixing is easier to construct and achieve.
本发明提供了一种能提高抗风能力的大跨度钢管混凝土拱桥结构及其施工方法，属于大跨度拱桥技术领域。为了解决现有拱桥单用抗风索相对于抗风索+阻尼器来说效果较差；大跨度拱桥在最大单悬臂施工状态的抗风效果较差的问题。机械强度低的问题。拱肋为两肢平行分布的钢拱肋，拱肋桁架弦杆的截面为箱型结构，拱肋与桥墩通过若干个抗风索连接。可在降低成本的情况下，保证大跨度拱桥的抗风性能；适用的工况较为广泛，水面或地面均通用，相对于需要将抗风索固定在拱桥附近的地面来说，既可降低施工难度，也可缩短工期，且不会因为拱桥在水面时不易固定抗风索的情况发生，自体抗风索固定更易施工和实现。
