摘　　要：有吊杆参与的桥梁结构均存在结构线型调整与吊杆索力优化问题,吊杆张拉状况很大程度上可决定桥梁结构最终的外形和内力分布情况。以钢管混凝土拱桥吊杆施工优化关键技术为对象,研究吊杆施工初始张拉力的确定以及不同吊杆张拉顺序对成桥状态的影响。The problems of adjustment of structure linetype and optimization of cable force of suspenders exist in all bridge structures with participation of suspenders,and tension of suspenders can decide ultimate outline and distribution of internal force of bridge structures to a great extent.With key techniques for construction optimization of steel pipe concrete arch bridge suspenders as objects,this paper researches determination of initial tensioning force of suspender construction and influences of different orders of suspender tensioning on completion states of bridges.

关 键 词：吊杆 钢管混凝土桥 初始张拉力 索力优化
