| 摘 要： | 由于受附近车站和隧道的高程控制,铜九铁路在以小角度跨越318国道时,不得不采用建筑高度低的大跨结构桥梁,为了同时满足一跨跨越318国道和不抬升隧道、车站的高程的要求,采用了建筑高度低、刚度大的(40 64 40)m单线预应力混凝土连续槽形梁结构,介绍该结构的设计情况。

| Abstract: | Limited by the elevation of the railway station and tunnel nearby,when Tongling-Jiujiang Railway spans the National Road 318 in a small angle,the long span bridge of low building height has to be used for the Railway.To simultaneously cater for the requirements that the bridge can span the National Road in one span,the elevation of the railway station and tunnel will not be raised,the bridge is adopted with a single-track prestressed concrete(PC) continuous channel girder structure with span arrangement(40 64 40) m,and of low building height and great rigidity.In this paper,the design of the girder structure of the bridge is described. |
