摘　　要：拱桥从古代发展直径已经历3000多年的发展历史。现代拱桥的跨境不断扩大,钢筋混凝土拱桥缆索在进行吊装施工时,单肋、双肋的稳定性要求也不断提高,成为影响拱桥合龙施工质量的关键因素。文章以上海康宁路蕴藻浜大桥为例,对换桥单基肋合龙施工稳定性进行分析,希望能够为相关工作提供一定的参考和借鉴。Arch bridge has gone through three thousand years of development history from ancient development diameter.The stability of single ribs and double ribs is also increasing constantly, which is the key factor to the construction quality of the arch bridge in the construction of the reinforced concrete arch bridge cable during the hoisting construction. This paper analyzes the construction stability of the single-base ribs of the arch bridge by taking the Yunnabang Bridge of Coming Road in Shanghai as an example, hoping to provide some reference and reference for the related work.
