| 摘 要： | 锚碇锚固系统是大型悬索桥主缆的承力构件,是悬索桥的生命线工程。悬索桥隧道锚中多采用弯束状的预应力钢束,与顺直管道的预应力钢束相比,锚固系统在设计上、生产上、施工上增加很大困难。本文介绍弯束可换式锚碇锚固系统在湖南矮寨特大悬索桥上的应用情况,借此总结经验,为以后相似的工程提供借鉴

| Abstract: | The anchorage system is the load-bearing component of the main cable of a large Suspension bridge and the lifeline project of a Suspension bridge. The curved prestressed steel tendons are mostly used in the tunnel anchors of Suspension bridge. Compared with the prestressed steel tendons of straight pipes, the anchorage system is more difficult in design, production and construction. This paper introduces the application of the bending bundle exchangeable anchorage system on the Aizhai Super Suspension bridge in Hunan Province, and summarizes the experience to provide reference for similar projects in the future |
