摘　　要：以黄良铁路刚构连续梁桥设计为研究对象,针对小清河分洪区的特殊需求,提出将行洪通道内的路基改造为桥梁的方案。通过优化梁部截面布置和墩台设计,提高了结构的整体性和刚度,同时降低了梁部高度,适应了分洪区的行洪需求,总结了刚构连续梁桥在铁路工程中的应用特点及关键技术,为类似工程的设计与施工提供了参考。This paper focuses on the design of the Huangliang railway continuous rigid-frame bridge,proposing a scheme to replace the embankment within the flood discharge channel with a bridge structure to address the specific needs of the Xiaoqing River flood diversion area.By optimizing the girder cross-section layout and pier design,the structural integrity and stiffness are enhanced,while reducing girder height to accommodate flood discharge requirements.This paper summarizes the application characteristics and key technologies of continuous rigid-frame bridges in railway engineering,providing a reference for the design and construction of similar projects.
