郑州陇海路高架160m 特大连续梁桥设计

摘要

连续梁桥由于施工技术成熟、经济指标优越，在国内外有大量的应用，但主跨超过150 m的连续梁桥较少。郑州市陇海路高架跨南水北调特大桥，主跨160 m ，采用悬臂浇筑施工。结合工程实践，分析特大跨径连续梁桥的方案选型、结构设计难点及施工要点，为同类型大跨连续梁桥施工提供参考。%Continuous beam bridge with superior construction technology of mature and economic indicators ,there are a large number of applications at home and abroad .But main span more than 150 meters of continuous girder bridge is still rare ,Zhengzhou city Longhai road elevated across water bridge , main span 160 m ,using the cantilever construction .Combined with engineering practice ,the analysis of large span continuous girder bridge scheme selection ,structure design and construction key points and difficulties provide a reference for similar long -span continuous girder bridge .
