曲线连续刚构桥结合了曲线桥和连续刚构桥的特点,因此在施工控制的过程中预拱度及立模标高的确定变得复杂。本文结合凉台河大桥工程实例,通过建立有限元空间模型,对比分析曲线桥梁在施工过程中结构位移与内力变化与直线桥梁的不同之处,为同类桥梁施工控制提供一定的参考。

The curved continuous rigid frame bridge has its special structural features,to make sure a certain pre-deflection and level becomes complicated during the process of the construction.In combination with the Liang Tai He Bridge Project in Hubei Province,the FEM simulation model is established.Compared with the straight bridge,the author analyzed the differences of displacements and internal forces during the construction process of the curved bridge,providing some ...
