| 摘 要： | 钢管混凝土拱桥的施工方法以缆索吊装法为主,扣索索力值的大小对成拱线形有着至关重要的影响。文中对扣索索力进行了静力平衡法和积分查表法2种方法的实例计算,并对计算结果作了分析与比较。从而得出静力平衡法产生误差的主要原因是模型简化,并分析了对扣索索力成桥线形的影响。

| Abstract: | At the present stage,erection with cableway is widely used in CFST arch bridges and the ca-ble force is very important to the arch shape.This paper calculated the cable force by two different ways,static balancing method and table look-up way.Through analyzing the results,the author drew a conclusion that the error of static balancing method is caused by cursory simplification and analyzed the cable force effect on the arch shape in brief. |
