| 摘 要： | 以益阳市康富南路跨线桥为实例，对钢管混凝土拱桥中吊杆索力随时间变化进行了分析．对比施工成桥时测得的吊杆索力、成桥3aNlg管混凝土拱桥随时间变化时测得的吊杆索力与成桥6a后测得的吊杆索力，分析得出：吊杆内力变化与系梁和铜管中混凝土发生收缩徐变有较大关系．

| Abstract: | Taking Kangfu South Road Viaduct at Yiyang for example, this article analyses the change with time of concrete-filled steel tube arch bridge suspender force. It contrasts the suspender force at the time of bridge construction with three years later and six years later, a conclusion has brought that the changes of suspender internal force is of ~reat relationship with shrinkaRe and creep of concrete filled steel tubular. |
