摘要
用空间分析模型 ,考虑了主缆和吊索的耦合效应和鞍座的影响 ,采用数值解析法对空间缆索悬索桥成桥状态和空缆状态主缆线形进行分析 ,然后通过算例验证了所提方法的正确性 .计算表明 ,该方法具有使用方便、计算速度快、精度高等优点 ,并适用于多跨空间缆索悬索桥。
In order to calculate the cable shape of suspension bridge with spatial cables at bridge completion stage and cable finish stage,a 3-dimensional analysis model is used and an numerical-analytical method is proposed,the effect of saddle and coupling between cable and hanger are also considered.The proposed method is verified through a numerical example and is shown of high accuracy,efficiency and conveniency.This method can also be used to analysis multi-span suspension bridge with spatial cables or with longitudinally inclined hagers and classical suspension bridge.
