世界跨径最大钢拱桥凤来大溪河特大桥钢桁拱合龙|无码少妇一区二区
中新社重庆11月27日电 (记者 郭虹 肖江川)27日，世界跨径最大的钢拱桥——重庆武隆至两江新区高速公路凤来大溪河特大桥钢桁拱成功合龙。
凤来大溪河特大桥全长1136.7米，主桥采用580米上承式钢箱桁架拱桥设计，为目前世界跨径最大的钢拱桥。大桥地处武隆区高陡深切峡谷地带，桥面距河面高差超310米，相当于100层楼的高度。大桥采用全钢结构，总用钢量2.5万吨。
中铁二院工程集团副总工程师、凤来大溪河特大桥总设计师陈克坚在现场告诉记者，设计选用更经济、更适合深山峡谷地形的钢拱桥施工方案，其受力更加明确、安全性相对可靠、施工相对方便。
据了解，在大桥建设过程中，施工团队攻克了全栓接钢桁拱桥节段应力和线形双控、有限空间桁片姿态调整、拱肋数字拼装与线形适时纠偏三大核心施工难题。
武隆至两江新区高速公路是重庆高速公路网中“四环二十二射六十联线”的第十六联线，建成通车后，将串联起仙女山、白马山等旅游资源，助力沿线特色农业及生态旅游产业发展。(完)
