大跨悬索桥锚固系统安装精度控制及施工关键技术研究

Research on Installation Precision Control and Construction Key Technology of Long-span Suspension Bridge Anchorage System

随着我国交通行业的高速发展,悬索桥这一桥梁类型在工程建设中越来越多,锚碇锚固体系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与耐久。依托在建的宜昌白洋长江公路大桥,针对其锚固系统的施工工艺与精度控制,系统地探究了施工过程的重点技术难点,总结出一套经济合理的大跨径悬索桥锚固系统施工工艺与精度控制方案,在实际工程中取得了良好的效果,对同类悬索桥锚固系统施工具有一定的参考意义。

With the rapid development of our country's transportation industry,more and more types of suspension bridges are used in engineering construction.Anchorage anchors are the lifeline of suspension bridges.The design and construction quality of a suspension bridge determine the safety and durability of the bridge to a large extent.Relying on the Yichang Baiyang Yangtze River Highway Bridge under construction,for the construction technology and precision control of its anchoring system,the key technical difficulties in the construction process are systematically explored,and a set of economical and reasonable construction technology and accuracy of the anchorage system for large-span suspension bridges are summarized the control scheme has achieved good results in actual engineering,and has certain reference significance for the construction of similar suspension bridge anchor systems.
