悬索跨越设计创新与完善

INNOVATION AND PERFECTION OF THE DESIGN OF SUSPENSION CABLE TYPE PIPELINE

在100m以上的大型管道跨越中,悬索跨越设计是大跨度管道跨越中的首选。忠武输气管道工程是国内管道施工最困难的工程之一,其中大型悬索跨越就有4座。笔者根据各自不同的地形地貌采用的设计创新及存在问题做一粗浅的分析。

Suspension cable type pipeline bridges are the most suitable for great pipeline bridges more than 100m.It is preferred in the design of pipeline bridge for its large span,rational stress,mature engineering and construction, and beautiful appearance.Zhongxian-Wuhan Gas Trans- mission Pipeline Project is one of the most difficult projects in China.It has four suspension cable type pipeline bridges,all of them are unique depending on the ground features.Some suggestions for the innovation and perfection of its design are put forward.
