【砥砺奋进的五年·重大工程】中国桥梁 世界点赞

2017-06-09 09:12:23   央视网

四川干海子特大桥

鹦鹉洲长江大桥

湘西矮寨特大悬索桥

不仅是港珠澳大桥,去年才通车的北盘江大桥,桥面距谷底达到了565米,相当于200层楼高,是世界第一高桥;四川干海子特大桥,世界第一座全钢管混凝土桁架梁桥,最高钢管格构桥墩达117米;鹦鹉洲长江大桥,世界跨度最大的三塔四跨悬索桥;湘西矮寨特大悬索桥,创四项世界第一。

国际桥梁与结构工程协会副主席同济大学教授葛耀君说,我们国家的桥梁(建设),正在从一个大国走向一个强国。随着国家“一带一路”经济的发展,使得我们甚至在未来的五到十年里面,在桥梁技术方面和桥梁建造的水平方面,有更新更大的突破。

这五年来,世界排名前10位的跨海长桥中,中国已经占据6座;这五年来,世界排名前10位的斜拉桥,中国已经占据7座;这五年来,世界排名前10位的悬索桥,中国已经占据6座。

而放眼未来,世界跨度最大的公路铁路两用大桥——沪通长江大桥预计2019年通车;主桥设置双层双向10车道、世界上通行能力最大的杨泗港长江大桥2019年也将建成。也就是说,未来,我们还有一大批世界级的桥梁正在路上。
