摘要
当前,新建铁路临近市区或车站地段,往往铁路密集、纵横交错,新建线路与既有铁路、公路小角度交叉的情况不可避免;加之临近车站时线路纵断面抬高困难,需严格限制上跨线路的结构建筑高度。钢横梁框架墩的建筑高度较低,而横向跨度相对较大,是此类工点较好的解决方案。本文介绍了钢横梁框架墩的结构特点,分析比较了不同的墩顶固结方式,并总结了设计注意事项。
There are many new-built railway lines which are near the city or railway stations, the dense railways crossing over each other and the small angle made by the new lines crossing over the existing railway or the highway is inevitable. Additionally, the line longitudinal elevation rising is difficult near the station, which needs the strict structure building height limit of the over crossing line. Steel crossbeam frame piers have a lower structure height and a larger span than routine frame piers, which is a better solution for such work. This paper introduced structural features of the steel crossbeam frame pier, analyzed and compared the different connecting methods for pier top, and summarized the design considerations.
