福元路湘江大桥梁拱组合桥顶推施工及受力研究

摘要

结合长沙福元路湘江大桥主桥工程,分析其顶推施工难点及总体施工工艺.利用有限元软件Midas/Civil建立多孔梁拱组合体系桥整体顶推施工计算模型,进行顶推施工受力研究.结果表明该桥顶推施工方案合理.%Combining with the construction of the main bridge of Fuyuanlu Xiangjiang bridge in Changsha, the challenges in jacking construction and overall construction process are analyzed. The finite element software Midas/Civil is adopted to simulate the integral jacking construction of porous beam-arch composite bridge and the research on the stresses of jacking construction are carried out. The result shows that the jacking construction program of the bridge is reasonable.
