摘要: 主缆无应力长度是影响结构成桥状态的重要参数,目前对主缆中心索股下料长度的计算已经有了比较成熟的研究,在以往研究的基础上提出了悬索桥主缆下料长度的精细化计算方法。首先,以索单元模拟主缆,基于结构目标成桥状态计算出中心索股主缆的无应力长度;其次,考虑锚端及主索鞍处主缆的实际空间位置分布,对主缆各索股无应力长度进行修正计算;最后,以一座自锚式悬索桥作为工程实例,对该精细化计算方法进行验证,给出了主缆各索股的精确下料长度。

Abstract: The unstressed length of the main cable is an important parameter that influences the finished state of bridge structure. At present, the calculation methods for the fabrication length of the main cable center strand have been well studied. Based on the previous studies, a fine calculation method for the fabrication length of the main cable was proposed. Firstly, the main cable was simulated by cable element and the unstressed length of the main cable center strand was calculated according to the finished state of bridge of target structure. Secondly, the unstressed length of each main cable strand was amended considering the actual spatial distribution of main cable at anchorage end and the cable saddle. Finally, the proposed calculation method was verified by taking a self-anchored suspension bridge as an example; meanwhile, the exact fabrication length of each main cable strand was given.

Key words: bridge engineering;self-anchored suspension bridge, finished state of bridge, fine calculation
