摘要
指出大跨度混凝土箱梁桥混凝土徐变对桥梁的合龙精度及成桥后的线形有着重要影响,对如何应用ANSYS有限元软件分析混凝土的徐变效应进行了研究,在此基础上,以某连续刚构桥为例,分析了徐变对跨中挠度的影响,得出混凝土徐变对大跨桥梁的跨中挠度影响显著的结论。
The important influence of the concrete creep in the long-span box-girder bridges on the closure accuracy and the line-shape after the project, the way of how to apply ANSYS finite dement software to analyze the creep effect of concrete is studied. On the basis of this, the influence of the creep on the mid-span deflection is analyzed by taking some continuous rigid bridge, and the conclusion that the concrete creep has obvious influence on the mid-span deflection of the large-span bridge.
