贵州这三座大桥“牛”到全世界，连外国专家都彻底服了！
The three bridges in Guizhou "Niu" have reached the whole world, even foreign experts have completely taken it!
我国在国际上有个十分有趣的名号，叫做“基建狂魔”。随着中国近些年来的高速发展，我们建造的工程很多都让世人觉得不可思议。今天我们来看看贵州三座让外国人觉得难以想象的桥梁工程。
Our country has a very interesting name in the world, which is called "infrastructure maniac". With the rapid development of China in recent years, many of the projects we have built make the world feel incredible. Today, let's look at three bridge projects in Guizhou that foreigners find difficult to imagine.
都格北盘江大桥：跨越贵州省六盘水市水城县都格镇和云南宣威市普立乡。大桥由云贵两省合作共建，全长1341.4米，桥面到谷底垂直高度565米，相当于200层楼高，也是世界最高的桥梁。
这里是喀斯特地貌区，沿江10公里的山体地貌石灰岩密布，山体硬度极差，为躲避遍布山体的溶洞和裂隙，最终将桥面定在这个令人眼晕的高度。
坝陵河大桥：位于贵州省安顺市高原重丘区，是沪瑞国道主干线上跨越坝陵河大峡谷的第一座特大型桥梁。
该桥为主跨1088米的单跨钢桁加劲梁悬索桥，桥梁全长1564米，桥面至坝陵河水面370米，建成时是居“国内第一，世界第六”的大跨径钢桁梁悬索桥。
该大桥为双向四车道，设计年限为一百年，桥梁抗风设计标准也按百年一遇的最大风速——每秒25.90米设计。全桥投资14.8亿元人民币，为贵州省内交通建设独立大桥投资之最。
鸭池河大桥：位于乌江源百里画廊，跨越鸭池河。
大桥桥面宽28米，全长1450米，主塔采用H型索塔，贵阳岸塔高243.2米、黔西岸塔高258.2米。
这座主跨长达800米、全长1450米的大桥是世界上最大跨径的钢桁梁斜拉桥，也是世界山区斜拉桥之最。
Duge Beipanjiang Bridge: It spans Duge Town, Shuicheng County, Liupanshui City, Guizhou Province, and Puli Township, Xuanwei City, Yunnan Province. The bridge is constructed jointly by Yunnan and Guizhou provinces with a total length of 1341.4 meters and a vertical height of 565 meters from the deck to the bottom of the valley. It is equivalent to 200 stories high and is also the highest bridge in the world.
This is a karst geomorphic area, along the Yangtze River 10 kilometers of mountain landform limestone dense, the hardness of the mountain is very poor, in order to avoid caves and cracks all over the mountain, the bridge deck will eventually be set at this dizzying height.
Baling River Bridge: Located in the High Plateau hilly area of Anshun City, Guizhou Province, it is the first super-large bridge across the Baling River Grand Canyon on Hurui National Highway.
The bridge is a single-span steel truss stiffened girder suspension bridge with a main span of 1088 meters. Its total length is 1564 meters. The bridge deck is 370 meters above the water surface of the Baling River. It was built as a long-span steel truss suspension bridge with "the first in China and the sixth in the world".
The bridge is a two-way four-lane bridge with a design life of one hundred years. The wind resistance design standard of the bridge is also designed according to the maximum wind speed once in a century - 25.90 meters per second. The total investment of the bridge is RMB 1.48 billion, which is the largest investment in the construction of independent bridges in Guizhou Province.
Yachi River Bridge: Located in Baili Gallery of the Wujiang River, it crosses the Yachi River.
The bridge deck is 28 meters wide and 1450 meters long. The main tower is H-shaped cable tower. The tower on Guiyang bank is 243.2 meters high and the tower on the west side of Guizhou province is 258.2 meters high.
This 800-meter-long and 1450-meter-long bridge is the largest steel truss cable-stayed bridge in the world, and the largest cable-stayed bridge in the mountainous areas of the world.
