Abstract

Abstract: This paper gives out a formula for calculation cable force according to concept Zero Moment,and discussing cable optimum point,the relation to cable force,cable point,tower height and tower distance.An example is given about a CFST arch at last.

Key words: segmental erection, cable point, optimum analysis, cable force

摘要： 根据"零弯矩法"概念,给出在拱肋节段吊装中关于扣索索力的计算公式,在此基础上讨论了扣索扣点最优位置、索力与扣点位置、塔高、塔距的关系,文末还用了一座钢管砼拱桥为例加以说明

关键词: 节段架设, 扣索扣点, 优化分析, 索力
