| 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3 a后钢管混凝土拱桥随时间变化时测得的吊杆索力与成桥6 a后测得的吊杆索力,分析得出:吊杆内力变化与系梁和钢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 great relationship with shrinkage and creep of concrete filled steel tubular. |
