拱作为压弯结构，随着跨径的增大，杆件的长细比及所承受的荷载也随之增大，拱圈横向刚度、宽跨比相对减小，在施工阶段及使用阶段横向稳定问题特别突出，常常成为拱桥设计的控制因素。

On the project background of Rongzhou Bridge, a half through CFST arch bridge in Yibin crossing Jinshajiang, the optimizing theory is applied to the calculation of the stayed-buckle-cable forces in the process of craning construction of the steel-tube arch segment and construction error adjusting. The calculated optimum cable forces with high precision can guarantee the inner forces and the structuredeformation in safe state, and ensure the line shape of the arch ring in accordance with design requirements as well.
