Application and Practice of Replaceable Main Cable Strand Anchorage Scheme in Self-Anchored Suspension Bridges
Abstrak
The main cable strands of self-anchored suspension bridges are typically anchored directly to the back of concrete or steel girders, a construction method that has durability issues. To address this problem, a new combined anchorage structure using finished cables and a connecting shaft is proposed. This anchorage structure is connected to the end of the main cable strands via the connecting shaft. This article provides a detailed description of the design concept and specifics of this new anchorage structure, including installation methods and procedures for removal and reinstallation during bridge operation. Full-scale static load tests validated the feasibility of the proposed design. This new structure improves the durability of the main cable anchorage section, allows for its replaceability, and can be extended to other similar applications, offering considerable reference value.
