| Abstract: | Research purposes:The technical of high speed railway with ballastless track is strong,it needs highly adaptability of structural rigidity,beam and rail. Research results:Concrete-filled steel tube A-shaped tied arch through railway bridge of Nielsen System is characteristic.Shape is beautiful,building height is low,and spanning capacity is strong.While it is also characterized by the following merits:exterior static structure,strong adaptability,large structural rigidity of both vertical and lateral directions,good handling performance to the track,cost-effectiveness,convenient construction and maintenance.So It can be applied in highway railway bridge Widely.The paper introduces the design of 112 m A-shaped tied arch bridge in detail. |
