装配式桥梁钢混组合梁施工技术

Construction technology of fabricated bridge steel mixed composite beam

长沙湘府路快速化改造工程主梁设计采用装配式钢混组合梁技术,在国内外桥梁中首次使用,如何有效控制钢混组合梁施工质量和安全,顺利实现装配式桥梁快速化目标,成为现场施工技术控制的重点和难点;文章以长沙湘府路高架桥为例,对装配式桥梁组合梁施工技术进行探讨,为同类桥梁施工提供借鉴。

The composite beam design of the Changsha Xiangfu Road rapid reconstruction project adopts the fabricated steel mixed composite beam technology.It is used for the first time in domestic and foreign bridges.How to effectively control the construction quality and safety of steel mixed composite beams and successfully achieve the goal of rapid fabricated bridge construction has become the focus and difficulty of on-site construction technology control.This article takes Changsha Xiangfu Road viaduct as an example to discuss the construction technology of fabricated bridge composite beams,and provides reference for similar bridge construction.
