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 文摘:斜拉扣掛在纜索吊裝中經常運用,但扣索索力多采用手工計算,且多用于5段以內的吊裝,計算復雜,精度低.本文提出“零彎矩法” ,可計算任意多段扣索索力,既可計算拱肋在施工過程中各節段臨時鉸接,又可計算各節段固結的情況,將兩種連接方式統一成一種計算方法,力學概念清楚,計算簡便,適宜程,文中最后用示例證實本方法的正確性
