    Abstract: 在橋梁結構設計時,一般利用影響線來確定活載重的臨界位置,進而得出斷面最大應力值,以作為斷面設計之依據,本文旨在利用數值分析模式,探討不同幾何形狀對斜張橋影響線分析結果之影響,另外,亦探討纜索及主梁材料參數變化對斜張橋影響線分析結果之影響。研究結果顯示,橋塔上的纜索錨碇段尺寸改變對斜張橋影響線分析結果之影響較大,另外,纜索材料參數改變對斜張橋影響線分析結果之影響較主梁材料參數改變之影響大。
    In bridge structural design, the engineer generally determined the critical position of the live load by using influence line, and then used it to calculate the maximum stress of the cross section of bridge. This paper is intended to use the numerical analysis model to investigate the effects of different geometry shape on the analysis results of influence line of cable-stayed bridge. Moreover, the effects of variation of Yong's modulus of cable and main girder on the analysis results of influence line of cable-stayed bridge are also investigated. The numerical results have shown that the variation of the length of the cable anchored zone on tower structure had more effects on the analysis results of influence line of cable-stayed bridge. Moreover, the results have also shown that the variation of Yong's modulus of the cable had more effect than that of the main girder.
