摘要
蒙华铁路龙门黄河大桥是全线的重点、难点和控制性工程。文章重点介绍了该桥的方案构思,提出中承式拱桥和悬索桥两种可行的桥式方案。对两种桥式方案进行比选分析,在满足重载铁路桥梁使用功能和防洪、通航、立交等要求的前提下,力求桥梁结构新颖,经济合理,与周围环境和景观协调,最终选定202m中承式拱桥为推荐方案。
Longmen Yellow River Bridge on Haolebaoji-Ji'an Railway is the key,difficult and control project of the uhole line.In this paper,the design of the bridge are introduced,two feasible bridge schemes are put forward,which are half-through arch bridge and suspension bridge.Through comparison and analysis of the two schemes,on the premise of satisfying the requirements of using function,flood control,navigation and interchange of heavy haul railway bridges,the 202 m half through arch bridge is selected as the recommended scheme,considering a novel structure and reasonable economy as well as coordinating with the surrounding environment and landscape.
