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
