catenary section

The segmental catenary method is adopted,by considering cable s geometrical non-linearity,to determine the alignment of cable under self-weight and static load,also to find the length of stress-free cable.

针对主缆索的几何非线性,采用较为精确的分段悬链线法计算其空缆线形、成桥线形及无应力索长。

According to actual stress characteristics of the self-anchored suspension bridge,this paper mainly presents the calculation method of the length of main cable-the segmental catenary method.

根据自锚式悬索桥的实际受力特点,介绍了主缆长度的计算方法——分段悬链线法。
