摘要
以某城市高架跨铁路桥梁为工程背景,采用有限元软件Midas Civil建立曲线梁计算模型,得到了转体前桥梁不平衡弯矩,提出了对平面曲线转体桥梁偏心设置计算的误差修正项,分析了小曲线半径、大纵坡转体桥梁设计过程中的要点,对转体系统施工过程的注意事项进行了总结。
Taking an elevated railway bridge in a city as an engineering background,the paper uses the finite element software Midas Civil to establish a curve beam calculation model,obtains the unbalanced bending moment of the bridge before the rotation,puts forward the error correction term for the eccentric setting calculation of the plane curve rotation bridge,analyzes the key points in the design process of the small curve radius and large longitudinal slope rotation bridge,and summarizes the matters needing attention in the construction process of the rotation system.
