摘要: 以国内某快速化改造项目为背景，详细分析讨论了组合梁上部结构的设计要点。结合实际情况，对结构体系、断面形式、施工措施等进行了深入研究，介绍了设计的方法和内容，总结归纳了跨路口组合梁桥上部结构设计经验。

Abstract: Based on an urban expressway project, the design essentials of the superstructure of the composite beam bridges are analyzed and discussed in detail. Combined with practical conditions, in-depth research was conducted on the structural system, cross-section types and construction measures. This paper elaborates on the design methods and contents and summarizes the design experience of the superstructure of composite beam bridges spanning road intersections.
