摘要
以合理拱轴线为目标函数的优化计算模型得到预抬高值,对拱轴线的控制达到了很好的效果,定长扣索法施工在钢管拱肋合理成拱方面是行之有效的。
Camber of the arch bridge is worked out with the help of optimization calculation method that adopts proper arch axis as the objective junction. The successful control of the arch axis proves that invariable cable method is effective in hoisting CFST arch ribs into arch bridge with proper camber.
