Erection Technology of Orthotropic Steel Deck for Continuous Beam Bridge with Existing Truss System

以九江长江大桥的桥面维修更换为背景,应用有限元软件Midas建立全桥有限元模型,对影响桥梁强度的关键因素温差效应所涉及的施工工艺进行优化,并取得了显著成果,为后续桁架体系连续梁的施工建设提供了范例。

Taking the bridge deck maintenance and replacement of Jiujiang Yangtze river bridge as the background,the finite element model of the whole bridge is established by using the finite element software Midas to optimize the construction technology involved in the temperature difference effect,and remarkable results have been achieved,to provide an example for the construction of the continuous beam of the truss system.
