南京青奥公园步行桥圆弧形斜钢塔安装施工技术研究

Installation Construction Technology of Skew Steel Tower of Nanjing Youth Olympic Park Pedestrian Bridge

南京青奥公园步行桥采用双塔双索面斜塔斜拉桥结构,该桥采用支架施工超大圆弧形斜塔。文章介绍该桥钢塔安装施工技术,重点介绍斜塔安装支架搭设、斜塔节段吊装等施工工艺,以期为同类型桥梁施工提供借鉴。

Nanjing Youth Olympic Park pedestrian bridge is a cable-stayed bridge with double pylons and double cable planes. The large arc shaped tower was constructed by bracket construction technology. This paper introduced installation construction technology of steel pylon, including support setting and segment lifting. It could be taken as reference for similar bridge construction.
