摘　　要：在钢管混凝土拱桥施工中,无支架缆索吊装斜拉扣挂法施工目前使用最多。以东莞水道特大桥为例,详细介绍了钢管拱肋悬拼过程中的扣挂系统,分析了扣索索力及塔架的强度及稳定性,为同类工程临时结构的设计提供了参考。The construction method of non-bracket cable-stayed is often used in the long-span CFST arch bridges. By way of example of the extra-large bridge on Dongguan watercourse, the fasten and hang system used in the process of suspending and connecting for steel tube rib are introduced respectively,analyzes the cable force, the strength and stability of tower in this paper.
