摘要： 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.本文提出"零弯矩法",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,又可计算各节段固结的情况,将两种连接方式统一成一种计算方法,力学概念清楚,计算简便,适宜编程,文中最后用示例证实本方法的正确性.

关键词: 斜拉扣挂, 零弯矩法, 仿真计算

Abstract: 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.This paper puts forward "Zero moment Method",which can not only calculate more segmental soupe force,but both temporary joint and fixed joint during construction.The Mechanical concept is clear,and it is easy for calculating.It is fit for program,and the illustrations prove that the methods are right.

Key words: cable-stayed, zero moment method, simulate calculation
