| 摘 要： | 研究目的:贵广铁路东平水道特大桥为(85.75+286+85.75)m双拱肋钢桁架拱桥,桥面采用带水平K撑的正交异性板结构,该桥式结构在国内是首次应用。通过对该桥主桁、桥面系和纵横向联接系进行受力特征分析,以及对受力复杂的G11节点进行局部精细空间有限元分析,为该桥的设计提供了依据,研究结果可供其他同类型桥梁参考。研究结论:该桥主桁杆件轴向受拉和受压的最大绝对值比较接近;受力状态比较合理,桥面系各构件受力均满足设计要求;G11节点局部受力情况复杂,各构件最大应力均未超过钢材的屈服应力。

| Abstract: | Research purposes:The Dongping Waterway Bridge on Guiyang-Guangzhou Railway,with a span arrangement of(85.75+286+85.75) m,is a steel trussed arch bridge with double arch ribs.The orthotropic deck structure with transverse K-shape brace is adopted to the bridge deck.This kind of bridge structure is the first time to adopte in China.In this paper,the mechanic behaviors of the main girder,bridge deck system and longitudinal and transverse connections are analyzed,and also the G11 joint which bears complicated ... |
