桥梁设计与建造是高速铁路建设的关键。在京津城际铁路桥梁、武汉天兴洲公铁两用长江大桥、南京大胜关长江大桥等建设实践中，广泛借鉴世界高速铁路桥梁的先进技术和成功建设经验，在建设理念、技术标准、设计特点、技术运用等方面，进行深入的研究和积极的探索，并得到了充分地运用，逐步形成了具有中国特色的高速铁路桥梁建设关键技术。

Bridge design and construction are key to high speed railway engineering. During the process of a series of bridge-building experiences such as Beijing-Tianjin intercity railway bridge, Wuhan Tianxingzhou bi-purposed bridge over Yangtze River and Nanjing Dashengguan bridge etc.,we have borrowed sophisticated technologies and successful experiences from all around the world and carried out in-depth study and research on ideas and concepts, technical standard, design characteristics and applications of technologies, thus key technologies for high speed railway bridge with Chinese characteristics gradually took shape.
