Construction Technology of External Cable Installation of Steel-concrete Composite Beam

摘要:

随着我国桥梁建设工程的高速发展，体外索在桥梁结构中的运用逐渐增多，施工工艺也不断提升。结合柳州市凤凰岭大桥工程实例，系统介绍钢混组合梁梁体外索预埋、下料、穿索、张拉的施工工艺，总结施工关键技术，为同类型桥梁施工提供了技术支持。

Abstract:

With the rapid development of bridge construction in China, the application of external cables in bridge structure is increasing, and the construction technology is also improving. Based on the engineering example of Fenghuangling Bridge in Liuzhou, the construction technologies of pre-embedding, cutting, crossing and tensioning of external cable of steel-concrete composite beam are systematically introduced, and the key construction technologies are summarized, which provides the technical support for the construction of the similar bridges.
