摘　　要：湖南省娄底市跨新星南路立交桥为一座三跨连续钢箱梁桥,为综合避免正交异性钢桥面板疲劳开裂与沥青混凝土铺装层频繁破损两大问题,该桥使用了新型的钢-STC组合桥面结构。论文以跨新星南路立交桥为背景,探讨了桥的钢箱梁设计及桥面设计,介绍了钢-STC组合桥面技术在三跨连续钢箱梁中的施工工艺。The overpass cross Xinxing South Road in Loudi City, Hunan Province is a three-span continuous steel box girder bridge. In order to comprehensively avoid the two major problems of orthotropic steel deck fatigue cracking and frequent damage to the asphalt concrete pavement, the bridge uses a new type of steel-STC composite deck structure. This paper takes the overpass crossing Xinxing South Road as the background, discusses the design of steel box girder and bridge deck, and introduces the construction technology of steel-STC composite bridge deck in three-span continuous steel box girder.
