摘　　要：悬索桥是目前特大跨径桥梁中的一种,已有成功建设实例证明其具有较好的安全性和稳定性。但由于悬索桥结构较为复杂、对施工工艺有严格要求,如在实践中出现施工不规范等情况,则会严重导致桥梁质量下降,危及后续使用安全。针对悬索桥锚碇施工技术进行研究分析,重点探讨重力式锚碇基础、锚固体系、锚体混凝土施工、隧道式锚碇施工工艺锚碇混凝土施工精度等关键要点,旨在为相似工程项目开展标准化施工提供一些借鉴和参考。Suspension bridge is one of the super long span bridges,which has been successfully constructed and proved to have good safety and stability.However,due to the complexity of the suspension bridge structure,there are strict requirements for the construction technology.If the construction is not standardized in practice,it will seriously lead to the decline of bridge quality and endanger the safety of subsequent use.In view of this,this paper conducts research and analysis on the construction technology of suspension bridge anchorage,and focuses on the key points such as gravity anchor foundation,anchorage system,anchor body concrete construction,tunnel anchor construction technology,anchor concrete construction accuracy,etc.The purpose is to provide some reference for similar projects to carry out standardized construction.
