| 摘 要： | 吊杆初始张拉力的确定是系杆拱桥施工过程中的关键问题。而在吊索外增加钢套管保护,则会给施工过程中索力的测量造成较大困难。结合一座钢管混凝土系杆拱桥,对外带钢套管的半刚性吊杆初始张拉力进行了优化分析和计算,并提出一种半刚性吊杆索力测量方法。通过在苏州市兴贤大桥施工监控过程中的应用,证明该测量方法方便、适用,可为同类工程提供一定的借鉴。

| Abstract: | The determination of the initial tensioning force in hangers is vital in the building of the tied-arc bridge.If the steel tube is applied in the outer hanger for protection,it will be more difficult to measure the initial tensioning force of hangers in the construction of the tied-arc bridge.In this paper,based on a concrete filled steel tube arch-tied bridge,the initial tensioning force in hangers is optimized and calculated,and a method for measuring the tensioning force in the semirigid hangers is propos... |
