“xaxسىكىش”“世界第一拱xaxسىكىش”广西天峨龙滩特大桥获国际大奖

  中新xaxسىكىش网南宁11月14日电(xaxسىكىش刘娜利 陈正 涂兵)广西大学提供的信息显示,近日在瑞士苏黎世举行的2024年度国际桥梁及结构工程协会(IABSE)颁奖典礼上,广西天峨龙滩特大桥摘得IABSE大型公路与铁路桥最高奖。

  天峨龙滩特大桥是世界首座跨径超600米的拱桥,实现了混凝土拱桥的“百年跨越”,成为世界拱桥发展史上又一座里程碑及中国桥梁国家“新名片”。

  天峨龙滩特大桥由中国工程院院士、广西大学土木建筑工程学院教授郑皆连担任总设计师,广西交通投资集团有限公司建设、广西交通设计集团有限公司设计、广西路桥集团有限公司施工。

  天峨龙滩特大桥是广西南丹至天峨下老高速公路的控制性工程。大桥主桥为上承式劲性骨架混凝土拱桥,计算跨径600米,创拱桥跨径世界纪录,比国外最大跨径混凝土拱桥——前南斯拉夫KRK桥跨度大210米,把混凝土拱桥世界纪录一次提高155米。

  据悉,天峨龙滩特大桥在建造过程中,攻克了系列科技瓶颈,在劲性拱骨架强劲度选择、外包混凝土浇筑、外包混凝土材料、降低混凝土应力水平和拱肋纵向配筋优化等方面实现了系列重大技术创新,取得了显著的技术和经济效益。(完)
