摘要
以某城市互通立交中一联主跨50 m的连续钢箱梁匝道桥为例,从结构构造设计、结构总体计算和梁体倾覆稳定性等方面进行分析研究,总结小半径曲线上钢箱梁匝道桥设计的特点,为类似项目提供参考。
Taking a continuous steel box-girder ramp bridge with a main span of 50 m in a city interchange as an example,analysis and research are conducted from the aspects of structural design,overall calculation of structure and beam overturning stability,and the steel box on the small radius curve.The characteristics of the beam ramp bridge design provide a reference for similar projects.
