Abstract

Abstract: In the flat coupling and precast slab installation of steel truss girder suspension bridge, the regular construction lacks appropriate service platform; therefore, it is hard and dangerous for the construction of section connection because the safety protection measures are hard to set up. In the construction of steel truss girder of Hulukou Bridge, the flat coupling installation system was firstly designed and applied. The proposed system ensures the construction safety and saves the construction time, which has high applicability and promotion significance in the construction of similar bridges.

Key words: bridge engineering, suspension bridge, steel truss girder, flat coupling installation system

摘要： 钢桁梁悬索桥上平联及桥面板安装常规施工缺乏操作平台，难于设置安全保护措施，给节段连接施工带来相当大的难度及安全隐患。葫芦口大桥钢桁梁施工首次自行设计并使用平联安装吊架，保证了施工安全的同时，节约了工期。该系统体现出较高的适用性，具有在同类桥梁施工中推广意义。
