壮哉中国桥:五年内新建九万座 穿云跨海行天下

2017-08-11 08:14:37   央广网

在浙江,自2010年建成通车以来,杭州湾跨海大桥的日均车流量超过5万辆。它缩短了宁波至上海间的陆路距离100多公里,对长江三角洲经济一体化和产业结构的调整、升级起到极大促进作用。

随着自身实力的增强,中国桥梁建设企业也在近年来更加积极地走出去,到世界舞台一展身手。2014年底,由中国交建承建的泽蒙—博尔察大桥建成通车,结束了近70年来贝尔格莱德市多瑙河上仅有一座大桥的历史。这座中国在欧洲修建的第一座大桥,被当地官员形容为“塞尔维亚近几十年来最好的基础设施项目”,更被当地百姓亲切地称作“中国桥”。马来西亚槟城二桥、巴拿马运河三桥、新奥克兰海湾桥……放眼五洲四海,近年来中国建设者主持或参加建设了一个个国际知名桥梁工程,赢得了全球同行的广泛赞誉。

云南普立大桥

“串起一条黄金旅游线”

耸立于高山峻岭之巅,穿行于云雾峡谷之间,位于G56杭瑞高速上云南宣威市普立乡境内的普立大桥,是国内山区高速公路首座钢箱梁悬索特大桥。

大桥桥面离峡谷485米,于2015年8月25日正式通车。

普宣高速公路全线建成通车后,从云南宣威至贵州边界4小时的车程缩短为1小时内,不仅给交通带来便利,还成为杭瑞高速公路上的重要景观,同时将遵义、六盘水、曲靖、昆明、大理、瑞丽等旅游景区串连起来,形成一条黄金旅游线路。

据不完全统计,通车后,仅是前来参观普立特大桥的市内外游客就达15万人次左右。“我们在这里生活了几十年,过去想要到山对面,需要四五个小时,大桥通车之后,一个小时就能到了,再也不用翻山绕远路了。”普立乡普立村村民缪祥寿说。

福建泉州湾跨海大桥

“加快区域经济圈形成”

湛蓝的泉州湾上,一座全长26.7公里的大桥如长虹般飞架南北。这座2015年5月12日通车的泉州湾跨海大桥,已满两周岁。

“大桥贯通后,连接了晋江、石狮、惠安、台商投资区等泉州经济最活跃、发展最快的环湾区域。”陈江握表示,泉州湾南北两岸通途坦荡,环城高速公路闭合成环,将直接加快环泉州湾980平方公里经济圈的闭合和形成,助力泉州“21世纪海上丝绸之路”先行区的建设。

贵州清水河大桥

“回家再也不用兜大圈”

2015年12月31日,贵州省清水河大桥正式通车,标志着贵州成为西部地区第一个县县通高速公路的省份。大桥全长2171.4米、主跨1130米,横跨清水河大峡谷,桥面至谷底深达406米,是世界第二高桥。

受困于复杂的喀斯特地质构造,大桥在建造之初,工程师们发现根本找不到让大型起吊设备进入施工现场的通道。“最终只能像搭积木一样,将所有材料化整为零。”清水河大桥总设计师郭俊礼介绍,清水河大桥在悬索桥建筑史上首次采用了板桁结合技术。

“现在过桥只需要3分钟,以前回老家必须得绕道贵定、福泉等地,相当于兜了个大圈子。”在贵阳工作的瓮安人侯显军说,大桥贯通后,贵阳到瓮安车程从以前的4个半小时缩短至1小时。
