南京大胜关长江大桥6～8号主墩基础设计

Design of the Pier 6～8# of the Nanjing Dashengguan Yangtze River Bridge

介绍南京大胜关长江大桥6跨连续钢桁拱桥6～8号3个主墩的基础结构形式,并结合主墩基础结构的受力特点和施工方案,对主墩基础成桥及施工状态的结构进行检算,合理控制主墩基础结构的受力。

This paper introduces the design of piers 6～8# of the Nanjing Dashengguan Yangtze River Bridge, a six-span continuous steel arch truss bridge. The structural verification analysis of the main pier foundations under construction and completion condition is introduced by exploring the force properties and construction design of the main pier foundation structure.
