摘　　要：钢混结合段是混合梁构造的关键部位。结合石首长江公路大桥主梁结构特点及受力特性,及超大跨度斜拉桥主梁钢混结合段既有研究成果的基础上,拟定了该桥主梁钢混结合段构造,通过受力计算分析,验证该钢混结合段结构的安全性,并总结了石首大桥主梁钢混结合段的设计特点和先进性。The steel-concrete composite section is the key part of composite girder structure. Based on the structural characteristics and mechanical properties of the main girder of the Shishou Yangtze River Highway Bridge, and the existing research results of main steel-concrete composite girder structure of the super-long span cable-stayed bridge, the structure of the main steel-concrete composite girder of this bridge is proposed.The stress calculation and analysis verify the safety of this structure of steel-concrete composite section. And the design characteristics and advanced nature of the main steel-concrete composite girder structure of Shishou Bridge are summarized.
