摘要
悬索桥锚碇锚固系统是悬索桥的生命线工程,其设计、施工质量在很大程度上决定了桥梁的安全性与耐久性。为提高结构的可靠性和耐久性,官山大桥隧道式锚碇锚固系统首次采用型钢锚固系统,定位系统安装精度要求高、施工难度大。重点介绍了型钢锚固系统的设计与安装关键技术,解决了在空间受限的锚碇洞室内系统锚梁及锚杆安装施工技术难题。
The anchorage fastening system is a lifeline engineering to a suspension bridge, for its design and construction quality may decide the safety and durability of the bridge to a great extent. In order to improve the structure＇s reliability and durability, the tunnel anchorage fastening system of Guanshan bridge is designed as an innovative formed steel fastening system, which requires a high accuracy in location. This paper describes the key technology of the anchor beam and anchor rod installed and constructed in the cramped and tilted tunnel anchorage cave.
