摘要
结合客货共线铁路特点,从截面选型、桥面布置、箱梁设计特点等方面进行分析,对挡砟墙、电缆槽等构造特点进行介绍,特别是大吨位锚具在设计中首次推广使用,为简支梁设计优化提供了方向。客货共线铁路简支箱梁设计不仅能够缩短桥梁施工工期,而且易于控制施工质量,是对客货共线铁路建设中组合T梁结构形式的必要补充。
Combined with the characteristics of mixed passenger and freight railway,this article analyses the selection of cross-section,bridge deck arrangement and design features of the box beam,and the structural features of the ballast retaining wall and cable trough are introduced. In particular,large tonnage anchorage is used for the first time in the design to provide reference for the design and optimization of simply-supported beam. The design of simply-supported box beam on mixed passenger and freight railway can not only shorten construction period,but also control construction quality. Thus,it is a necessary complement to combined T beam structure on mixed passenger and freight railway.
