新建铁路与既有铁路小角度交叉,一般采用框架墩+简支梁的桥跨形式,但是框架墩结构高度高,本文提出的框架简支板桥能够很好地解决这个问题,并且从施工和设计角度论证了工程的可行性。研究结果:框架简支板在设计上强度、刚度满足规范要求,施工可行,具有较好的经济价值,值得推广应用。
新建鐵路與既有鐵路小角度交扠,一般採用框架墩+簡支樑的橋跨形式,但是框架墩結構高度高,本文提齣的框架簡支闆橋能夠很好地解決這箇問題,併且從施工和設計角度論證瞭工程的可行性。研究結果:框架簡支闆在設計上彊度、剛度滿足規範要求,施工可行,具有較好的經濟價值,值得推廣應用。

When new railway crosses the existing railway with a small angle, frame pier is generally adopted, but the frame structure is high. The frame structure with simply supported plate proposed in this paper may solve the problem properly and is proved applicable in prospective of construction and design. The research results demonstrate that the frame structure with simply supported plate satisfies the specification and is practical and economical.
