Construction method for converting self-anchored suspension bridge system in cable-beam cross construction
The invention discloses a construction method for system conversion of a self-anchored suspension bridge in cable-beam cross construction. The construction method comprises the following steps: S1, construction preparation work before system conversion; s2, bridge deck systems on the two sides are constructed; s3, the auxiliary suspender is tensioned step by step; s4, constructing a concrete bridge deck system of the navigable hole section; and S5, full-bridge suspenders are tensioned step by step, and the tension of the suspenders is adjusted. The method can be suitable for system conversion construction of the self-anchored suspension bridge, through auxiliary stress of the main cable and the suspender, namely, reinforcement is conducted only through the suspender of the bridge, other reinforcement facilities do not need to be arranged, the problem that the stress of the steel beam at the position of the large-span navigation hole of the self-anchored suspension bridge in the system conversion construction stage is too large is solved, and the construction efficiency is improved. The steel consumption can be greatly saved, the construction efficiency is improved, the construction cost is reduced, safe and rapid construction of self-anchored suspension bridge system conversion can be achieved, the practicability is high, and the applicability is wide.
本发明公开了一种缆梁交叉施工的自锚式悬索桥体系转换的施工方法，该施工方法包括如下步骤：S1、体系转换前的施工准备工作；S2、两侧桥面系施工；S3、辅助吊杆逐级张拉；S4、通航孔段的混凝土桥面系施工；S5、全桥吊杆逐级张拉及吊杆拉力调整。本发明能适用自锚式悬索桥的体系转换施工，通过主缆及吊杆的辅助受力，即：仅利用桥梁自有的吊杆进行加固，而无需设置其他加固设施，解决了自锚式悬索桥在体系转换施工阶段大跨径通航孔位置钢梁应力过大的问题，可以大幅节约钢材用量，提升了施工工效，降低了施工成本，能够实现自锚式悬索桥体系转换的安全快速化施工，实用性强，适用性广泛。
