摘要
以高墩大跨径曲线刚构桥为研究对象,以稳定性理论为基础,利用有限元法对其在施工阶段和营运阶段的稳定性进行计算分析;通过对不同墩高、曲率半径、不同构造、不同工况的稳定性计算结果进行比较,总结出高墩大跨径曲线刚构桥设计参数(墩高、曲率半径、系梁个数)与稳定性特征值(失稳荷载系数)的关系.
Based on stability theory, the paper analyzed the stability of curve rigid frame bridge with high pier and large span for construction and service phases by finite element method. Through comparison and classifying the results of different height of piers and different curvature radius and constitution, the relation of the stability eigenvalue coefficient and the design parameters and its constitution were summarized. It is the foundation of the bridge design.
