悬索桥与斜拉桥是当前大跨径桥梁的两种典型桥型,比较起来悬索桥更适合1000m以上的大跨度。大跨径悬索桥钢箱梁的安装主要采用跨缆吊机和缆索吊机,本文介绍了这两种吊机的特点、安装方法及钢箱梁的吊装技术与施工管理。
Suspension bridges and cable-stayed bridges are two typical bridge types of current large-span bridges. Compared with suspension bridges, suspension bridges are more suitable for large-span of more than 1000m. The installation of the steel box girder of the long-span suspension bridge mainly uses the cross-haul crane and the cable hanger. This paper introduces the characteristics of the two cranes, the installation method and the steel box girder hoisting technology and construction management.
