时速160km城际铁路简支T梁设计研究

简支T梁在客货共线铁路中广泛应用,将其应用于城际铁路桥梁中需要其满足城际铁路在环境、外观、空间上的要求。设计优化T梁的桥面布置和梁体结构,外侧支架采用钢-混凝土组合板结构,可安装声屏障。克服了常规T梁整体性不足的缺点,在经济上和施工灵活性上继续保持其一贯优势。其在城际铁路桥梁中有推广应用价值,并为其他铁路T梁设计提供借鉴。

Design and Research of Simply Supported T-Beam for 160 km/h Intercity Railway

Simply supported T beam is widely used in mixed passenger and freight traffic. Its application to the inter-city railway bridges should meet the requirements for environment,appearance and space.The design optimizes T beam deck layout and structure,the sidewalk steel support employs steel and concrete composite slab structure with sound barriers,which overcome the drawbacks of conventional Tbeam of insufficient integrity and maintain the advantages in economy and construction flexibility. It is of great value to be applied to inter-city railway bridges and can be referenced for the design of other railway T beams.
