主拱为桁架式双拱肋，钢管拱纵向分13段制造，采用无支架缆索吊机安装、钢绞线斜拉扣挂施工。
The steel pipe arch was manufactured in 13 segments vertically, erected by cable crane without support and clasped by diagonal tension steel strand.
斜拉扣挂在缆索吊装中经常运用，但扣索索力多采用手工计算，且多用于5段以内的吊装，计算复杂，精度低。
Cable stayed is used to cable suspension, but cable force is calculated by manual, and only for less than 5 segments, and the prescion is poor.
斜拉扣挂施工中索力计算复杂，根据“零弯矩法”概念，推导出拱肋节段吊装中各施工阶段扣索索力的计算公式。
On the basis of conception of zero moment, we can deduce the computational formula of the tension of cable in the different construction stage of the steel tube arch ribs.
拱肋纵向分7段预制，采用无支架缆索吊机安装、钢丝绳斜拉扣挂法施工。
The arch rib have been fabricated longitudinal by 7 segments, and used the non-support cable crane installation and the steel cable diagonal-tension method.
