摘　　要：钢混结合段的设计是混合梁斜拉桥的关键技术之一,钢混结合段的位置、类型及细部构造设计直接影响到桥梁的安全性和耐久性。结合宁波市福明路斜拉桥钢混结合段的设计,介绍钢混结合段位置的确定、结构形式的选择、细部构造及结构计算分析。分析表明本桥钢混结合段受力合理,传力平顺,刚度过渡平稳。The design of steel-concrete joint segment is one of the key technologies of a cable-stayed bridge with hybrid girder, while the design of location, type and detail structure of steel-concrete joint segment will directly affect the safety and durability of the bridge. This paper introduces the design of the steel-concrete joint segment of the Fuming Road cable-stayed bridge in Ningbo City, including the determination of location, the selection of structure types, the detail structure, the structure calculation and analysis of steel-concrete joint segment. The results show that this bridge structure is under rational stress state, the force transmission is smooth and the rigidity transition is steady.
