十字型墩在城市轨道交通中的应用

Application of Cruciform Pier in Urban Rail Transit

城市轨道交通高架桥多线道岔梁桥设计,由于道线空间上高度不一致,及受道路、管线等限界约束,其桥墩的布设非常复杂。以沿海某地市域铁路某车辆段线与正线并行段的桥墩设计为背景,研究并提出一种新的墩型-十字型桥墩,较好地解决了空间标高不一致的问题,满足限界要求,并减少对既有道路的干扰,即经济又美观。

The multi-line turnout beam of urban rail transit viaduct,has representative characteristicssuch as diverseheight in space,constraints by road,pipeline,and so on,that leadsto complexity workof pier design.Taking a train depot lines parallel with railway main linesomewhere in the coastal areaas the background,a new kind of pier shape-cruciform pier is researched and put forward.It solves well the problem of the inconsistent spatial elevation,and meets margin requirements.The piers can also minimize disturbance to the existing road,and achieve good effect of economy and beauty.
