| Abstract: | In view of the problem of poor durability of the prestressed anchorage system of suspension bridge in China, a new type of grease anti-corrosion prestressed anchorage system with good durability, more safety and reliability and characteristics of "detectable" and "replaceable" is proposed in this paper. The system has been tested by static and dynamic loading and deformation tests, installation, oil change and prestressed steel bundle construction tests, and the research results have been applied to the anchorage project of suspension bridge. |
