摘要 双线铁路梁式桥在位于单线逐渐过渡到双线的线路上时,其过渡段梁的曲线布置往往比较复杂。合理利用标准简支梁的适用条件,按线间距的大小调整过渡段的孔跨布置形式,对过渡段的每孔梁分别按梁端最大线间距等宽度布置,在不影响结构整体安全性的前提下,解决了单线至双线过渡段简支梁的曲线布置问题,避免了繁琐的曲线布置计算。 When a double-track single-track is gradually transited railway girder bridge is situated at to the double-track, the curve layout a transition section where the of the girder is generally much more complicated. In this paper, the service condition of the standard simple girders was fully utilized, the span layout on the transition section was adjusted according to the distance between centers of tracks, and each girder span on the transition section was laid out with equal widths respectively according to the maximum distance between centers of tracks at the girder end. As a result, the curve layout problem of simply-supported girder on transition section from single-track to double-track was able to be solved on the premise of not affecting the overall safety of the structure, and also the tedious curve layout calculation was able to be avoided.
