摘　　要：钢-混凝土组合结构,凭借其轻盈的自重、出色的延性及卓越的承载能力,充分发挥钢材和混凝土的双重优势,在桥梁建设领域中得到了广泛的应用。这种独特的组合结构,促使工程往往采取“纵向分段、横向分片”的分段吊装施工工艺,进而使得钢混组合梁的节段划分成为施工技术的关键所在。以梧州高速公路段钢混组合梁施工实际工程项目为依托,重点阐述组合梁的节段划分依据、不同的节段划分方式及其对施工过程的影响,同时,通过对比分析分段吊装施工与传统一次成桥工艺在变形控制上的差异,旨在为同类工程项目提供参考,并推动钢混组合梁施工技术的持续进步与优化。The steel-concrete composite structure,with its lightweight self weight,excellent ductility,and outstanding bearing capacity,fully utilizes the dual advantages of steel and concrete and has been widely used in the field of bridge construction.The unique structural form of this composite structure often leads to the adoption of the segmented lifting construction technology of“vertical segmentation and horizontal segmentation”in engineering,making the segmental division of steel-concrete composite beams the key to construction technology.This article is based on the actual construction project of steel-concrete composite beams on the Wuzhou Expressway section,focusing on the basis of segment division of composite beams,different segment division methods,and their profound impact on the construction process.At the same time,by comparing and analyzing the differences in deformation control between segmented hoisting construction and traditional one-time bridge construction technology,it aims to provide a solid reference foundation for similar engineering projects and promote the continuous progress and optimization of steel-concrete composite beam construction technology.
