    Abstract: 本研究基於薄壁梁理論、彈性基礎梁理論及虛功原理,主要探討具線性抗扭支承(Linear bearing)及單柱式點支承(Single column point bearing)之曲線連續梁橋在受力下之斷面應力行為利用中間支承處之位移協調條件建立變形方程式,從線性支承的觀念透過支承扭矩之反向加載來推導出點支承之解析方法,同時並考慮薄壁梁之翹曲及畸變效應,在實例之分析比較過程中,探討曲率半徑效應、橫隔梁間距、跨長大小、斷面深度等因素對線性及點支承橋梁應力特性的影響。
    The stress behavior in the section of curved continuous box girder with linear bearing and single column point bearing is to be analyzed by the thin-walled girder theory, elastic beam theory and the principle of virtual work. The deformation equations are established by the consistent conditions. The warping and distorsion effects will also be considered in this analysis. Through the use of this method of analysis to a practical case, the effects of radius of gyration, the spacing between diaphragms, length of span, the position of support and the width of deck upon the stress characteristics will be discussed and compared.
