平顶山市建设路东出口立交桥是一座主桥跨径为35 m+72 m+35 m的自锚式悬索桥,上部结构采用钢筋混凝土箱梁(梁体为单箱双室),缆索采用钢绞线外套钢管混凝土结构,锚固在主梁梁端和主梁跨中。本文结合该桥工程实例,探讨自锚式悬索桥存在的技术问题和解决办法。 The east exit overpass of Jianshe Road, Pingdingshan City is a self-anchored suspension bridge with a span of 35 m + 72 m + 35 m. The upper structure is reinforced concrete box girder (the girder is single box and double chamber), and the cable is made of steel strand Jacket concrete-filled steel tube structure, anchored in the girder end and the main beam. In this paper, the bridge project examples to explore the self-anchored suspension bridge technical problems and solutions.
