摘　　要：文章结合厦深客运专线韩江特大桥大跨度岔区变宽连续梁设计,探讨了桥上无缝道岔的设计技术难点,分析研究梁体结构形式、梁体刚度、岔桥位置及车岔桥动力特性等,较好解决了大跨度道岔区变宽连续梁结构复杂的关键技术,实现了梁体结构传力顺畅,避免了应力集中。Combining with the design on long-span varied-width turnout continuous beam on Xiamen-Shenzhen passenger dedicated railway,the paper discusses the key technology in design for bridge seamless turnout,analyses the bridge structure,beam stiffness,position and mechanical features of turnout bridge etc.and overcomes the difficulty in the design for the long-span varied-width turnout continuous beam to realize the mooth transmission for beam structure force and avoid stress concentration.
