摘要
介绍斜拉索的构造设计,比较标准抛物线、抛物线、无弹性悬链线方法在进行斜拉索角度修正时的计算差异。以郑州市郑东新区龙湖内环路上跨北引水渠桥工程实例为基础,进行参数分析,提出各个方法的适用范围。
The structure design of stay cable is introduced in this paper with comparing the calculation differences of stay cable angle correction by the ways of standard parabola, parabola and non elastic catenary. Based on the project case of Innerring Rd. over crossing North Diversion Canal Bridge in Zhengdong New Area, Zhengzhou, parameters are analyzed and the ranges of application of different method are provided in the end.
