摘　　要：为提高铁路枢纽上跨干线铁路的大节段连续梁悬灌控制能力,文中以银武连接线特大桥工程为背景,通过大节段悬灌浇筑法、全封闭挂篮法施工、设置合理挂篮结构。与此同时,实施严格的施工监测和安全防护措施,在保证安全的前提下完成高质量的施工,施工技术可为类似桥梁施工提供一定的参考。Taking the yinwu connection line grand bridge project as the case,we propose a construction technology for enhancing the control capability of large-segment continuous girders in cantilever casting over mainline railways at railway hubs,which employs the large-segment cantilever casting method and a fully enclosed form traveler sys⁃tem,supported by the design of a rational form traveler structure.Additionally,strict construction monitoring and safety protection measures are implemented.These efforts ensure high-quality construction while maintaining safe⁃ty,providing a valuable reference for similar bridge construction projects.
