摘要
兰合铁路祁家渡黄河大桥根据桥址处的地质条件、通航要求等,采用主跨180 m的上承式劲性骨架混凝土拱桥。设计中对该桥的拱轴系数进行详细研究,给出主桥的详细结构尺寸及主桥主要施工步骤,在此基础上采用Midas软件建立有限元模型进行计算分析,结果分析表明满足设计要求。
Considering the geological conditions and navigable requirements of Qijiadu Yellow River Bridge of Lanzhou-Hezuo Railway Bridge location, deck-type stiffened skeleton concrete arch bridge whose main span is 180m long was adopted. After careful research on the arch axis coefficient of the bridge, structural dimension and main construction procedure of the main bridge were described in details. Midas software was used to build the finite element model for calculation and analysis. The analysis result showed that the design requirements are well satisfied.
