| 摘 要： | 以高墩大跨径曲线桥为研究对象,以非线性稳定理论为基础,利用有限元法对其在悬臂施工阶段荷载状态进行计算分析;通过对不同曲率半径、墩高、系梁个数的非线性计算,对荷载比例系数和悬臂端计算结果进行比较分析,总结出高墩大跨径曲线刚构桥曲率半径、墩高、系梁个数与荷载系数、悬臂端位移的关系,为设计及施工提供科学依据。

| Abstract: | Based on nonlinear finite element theory,the stability of curve rigid frame bridge with high pier and large span for cantilever construction is analyzed by nonlinear finite element method.Through comparison and classifying the results of different curvature radius and height of piers and the number of tiegirders.The relation of the loads parameter to the curvature and height of piers and the number of tiegirders were summarized.It is the foundation of the bridge design and construction. |
