中承式集束钢管混凝土平行肋拱桥 ,桥道以上无横撑 ,国内尚不普遍。该文作为“集束钢管混凝土提篮拱桥”研究系列之一 ,探讨了结构性能、结构参数、设计与实践。拱肋钢管的“无级绳”吊运 ,桥道横梁“荡提法”安装 ,具有明显的技术、经济优势 ,较通常的天线吊装 ,节省费用 5 0 %以上。
In the type of concrete-filled steel tube bundle rib arch bridge, no span above the bridge, the country is not yet widespread. As one of the research series of “CFST arch bridge”, this paper discusses the structural performance, structural parameters, design and practice. Arch rib pipe “no-class rope” lifting, bridge beam “swing mention method” installation, with obvious technical and economic advantages, compared with the usual antenna hoisting, saving 50% or more.
