摘要
以曲线连续刚构桥为研究对象,基于欧拉弹性理论,利用有限元方法对桥梁在施工阶段和成桥阶段进行稳定性分析计算。通过不同曲率的稳定计算结果总结出曲率半径与稳定安全系数之间的关系。其结果可对曲线连续刚构桥设计与施工提供一定的参考。
Taking the curve continuous rigid frame bridge as the research object,calculate the stability in construction stage and completion stage base on the Euler elastic theory and by means of the finite element method.Summarize the relationship between the radius of curvature and the stable safety coefficient by means of stability calculation results of different curvature.The study may provide some references for design and construction of curve continuous rigid frame bridge.
