摘要
文中以牂牁江大桥悬索桥施工项目为例,系统分析了主梁施工初始偏差、主缆施工初始偏差、主梁结构自重及弹性模量偏差、吊索预应力张拉偏差等因素对成桥线形的影响,并提出针对性控制方案.相关研究成果可为同类悬索桥成桥线形施工控制提供参考.
Abstract
Zangke River Bridge construction practice was the basis for this paper to systematically analyze the influence of factors such as the initial deviation of main beam construction,the initial deviation of main cable construction,the self-weight and elastic modulus of main beam structure,and the prestress tension deviation of suspension cable on the shape of the completed bridge,and put forward a targeted pre-control plan,which achieved ideal results.The relevant research results can provide reference for the subsequent linear construction control of suspen-sion Bridges.
