| 摘 要： | 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．此方法可计算任意多段扣索索力，既可计算拱肋在施工过程中各节段临时铰接情况．又可计算各节段固接情况，计算简便，适于编程．计算中对拱肋自重采用积分法计算，避免了常用的简支梁模式计算中重心偏离的误差．并将此方法进行了具体应用． |
| 关 键 词： | 钢管混凝土拱桥 拱肋悬索 吊装施工 零弯矩法 索力 扣索计算 简支梁 |

| Abstract: | It is very complicated to calculate the tension of cable in the erection. 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. According to it, we can calculate the tension of cable not only when it is temporary stays but also when it is fixed. And it is very easy to calculate and suit to programme. Through the integral calculation to the deadweight of fibs. It can avoid the centroid departure error of the model of simply supported beam. |
| Keywords: | zero moment the teneion of cable temporary stays stays dead weight calculate moment through integral |
