摘　　要：某独塔双索面曲线斜拉桥位于3400m半径的圆曲线上,设置超高,其钢箱梁设计独特,该文重点介绍了该桥钢箱梁结构体系特点、主梁类型选择、结构计算、钢箱梁总体及局部构造设计及排水设计等。This paper introduces the steel box girder design of a curvilinear cable-stayed bridge with single-tower and double-cable planes. The bridge is located at a circular curve with radius of 3400 meters,so the design of steel box girder is unique. Structural system characteristics,selection of girder type,structural calculation,overall and local structure design of the steel box girder and drainage design are mainly introduced in this paper.
