摘　　要：锚固系统是悬索桥主缆索力与锚碇结构的重要传力系统,其施工质量控制尤为重要。目前国内外悬索桥重力式锚碇锚固系统主要有型钢锚固系统、预应力锚固系统和钢拉杆锚固系统等。以白洋长江公路大桥北岸重力式锚碇型钢锚固系统的安装施工为例,简要阐述了型钢锚固系统安装施工的工艺流程及方法,提出了施工过程中的重点控制环节及要点,可为类似工程提供借鉴和参考。The anchoring system is an important force transmission system for the main cable force and anchorage structure of the suspension bridge. The construction quality control is especially important. At present,the gravity anchor anchoring system of suspension bridges at home and abroad mainly includes steel anchoring system,prestressed anchoring system and steel rod anchoring system. Taking the installation and construction of gravity anchorage steel anchoring system on the north bank of Baiyang Yangtze River Highway Bridge as an example,this paper briefly expounds the process and method of installation and construction of steel anchoring system,and puts forward the key control links and key points in the construction process,provides reference for similar projects.
