摘　　要：城市景观桥梁的现实景观与构型选用,需要采用变高度异型刚架桥钢箱梁结构。以福州市岐阳一路景观桥为例,分析临地铁的桩基采用全回旋长护筒旋挖钻孔、钢箱梁锚固端安装与预应力张拉、箱梁工厂模块化的制作、节段的运输与安装等主要施工技术,研究变高度异型刚架箱梁景观桥施工的主要技术节点的符合性与可行性。The practical landscape and configuration selection of urban landscape bridges need to adopt the variable height profiled rigid frame bridge steel box girder structure.Taking Qiyang Road Landscape Bridge in Fuzhou as an example, This paper analyzes the main technical construction of pile foundation of Linlin Metro, such as rotary drilling with full-circle long protecting cylinder, installation of anchor end of steel box girder and prestress tension, modularization of box girder factory, transportation and installation of segments, studies the compliance and feasibility of the main technical nodes in the construction of variable height special-shaped box girder landscape bridge.
