摘　　要：调研国内外特大桥的应用现状,中国大跨度桥梁近15年来取得了巨大的成就,截至2019年12月,世界上已建成的大跨度斜拉桥前10座有7座在中国、世界上已建成的铁路/公铁两用斜拉桥跨径排名前8位均在中国、世界上已建成的大跨度悬索桥前10座有6座在中国。归纳与总结中国大跨度桥梁在新结构、新材料、新装备和新技术应用等方面的最新进展成果,在此基础上对中国大跨度桥梁的发展方向进行展望:大跨度桥梁建造技术将得到全方位的提升、大跨度桥梁基础将会多元化发展、更高强或新型材料将会用于大跨度桥梁、大跨度桥梁新装备与新技术将会不断涌现。The status quo of long-span bridges in China and overseas has been surveyed.As of December,2019,seven out of the top ten long-span cable-stayed bridges in service,the top eight rail-cum-road cable-stayed bridges superior in span lengths in service,and six of the top ten long-span suspension bridges in service are all in China.China has made great achievements in long-span bridges in the past 15 years.The latest developments and achievements of utilization of new structures,new materials,new equipment and new technologies in long-span bridges in China are summarized,based on which the development direction of the long-span bridges in China is envisioned.In the future,the construction technology of long-span bridges will get all-around improvement,diverse types of foundations will be used,higher strength or new materials will be tried and new equipment and technologies will increasingly be researched and employed for long-span bridges.
