摘　　要：绵阳三江大桥是由空间索面曲线钢箱梁人行斜拉桥和单索面混凝土箱梁车行斜拉桥叠置并共用桥塔组合而成的新型结构体系。该桥将斜拉桥的刚劲和曲线桥的柔美巧妙地结合,结构新颖,造型独特,富有韵味,具有较高的技术难度和科技含量。以绵阳三江大桥为例介绍叠层曲线组合斜拉桥设计的理念和关键技术。Sanjing River Bridge of Mianyang is a new structural system laminated of the spatial plane curve steel box girder pedestrian cable-stayed bridge and the single-plane concrete box girder vehicle cable-stayed bridge, and together combined of bridge and pylon. This bridge is ingeniously to combine the rigidity of cable-stayed bridge and the beauty of curved bridge. Its structure is new and its modeling is special with the rich flavor and with the higher technical difficulty and scientific technological content. The article introduces the design idea and key technology of laminated curve combined cable-stayed bridge.
