摘要
大连南部滨海大道工程锚碇基础采用重力式钢筋混凝土沉箱结构,重约26 000t,为目前国内最大悬索桥锚碇沉箱基础。在悬索桥施工领域首次采用这种超大钢筋混凝土沉箱基础,其起浮、拖运及安装等工艺尚无先例可以借鉴,通过物理模型试验得出各项参数,模型试验取得的各项参数与实际施工工况条件相结合,指导超大沉箱拖运安装施工。
The Dalian South Binhai Avenue project used gravity reinforced concrete caisson foundation as the anchorage.The foundation,with its weight of 26 000t,is the largest caisson foundation for suspension bridges in China.Being the first concrete caisson foundation of this size,there are no previous experiences for its floating,towage and installation.During this project,various parameters were obtained by physical model testing.These parameters are then used in combination with the practical construction conditions to guide the towage and installation of the huge caisson.
