摘要
南京大胜关长江大桥是京沪高速铁路上一座六跨连续铁路钢桁梁(拱)桥,采用混凝土与钢正交异性板相结合的整体桥面,多横梁体系,钢正交异性板与下弦杆焊连在一起。本文主要研究了该桥边孔84+84m三主桁连续钢桁梁桥正交异性整体钢桥面板的受力情况。利用空间有限单元法,对桥面系部分构件的受力情况进行了分析。计算结果表明:该桥的整体桥面结构满足高速行车要求;桥面系各构件受力合理。
Nanjing Dashengguan Yangtse River Bridge is a six railway lines and three main truss girder（arch） bridge on the Beijing-Shanghai high-speed railway. It takes the form of ballast integral deck with the orthotropic steel deck and bottom chords being welded together.In this paper, we mainly study the analysis on orthotropic steel deck of Three mail truss 84＋84m continuous steel truss bridge .we use the space finite element method to analysis and research the force situation on this orthotropic steel bridge deck. The results show that： The overall structure of the bridge deck meets the requirement of high-speed lane,and the force situation on every components of this bridge is reasonable.
