摘要
以沙湾特大桥为研究对象,采用桥梁博士3.0有限元程序,建立了该桥梁最大悬臂施工阶段和成桥阶段的有限元模型。对索力参数变化引起各主梁、主塔的敏感性进行分析,并提出了结构的变化趋势及原因。所得结果可以为同类桥梁设计和施工提供参考。
Shawang bridge is take of for study to establish Bridge program-the maximal cantilever construction stage and the sensitivities are analyzed by taking changes of the parameters of cause of the structure. The valuable conclusions can provide the bridges. two stage＇s FEM models of this bridge by the Dr completed stage. The main girder and mail tower＇s cable force, in addition to propose the trend and reference to the design and construction of similar
