Tsing Ma Bridge in Hong Kong-the longest suspension bridge in the world
Is the Tsing Ma Bridge for Red? A world-class building built at Cape Airport. It spans Tsing Yi Island and Ma Wan, with a total length of 2,200 meters. It is the longest traffic and railway suspension bridge in the world. The best scenic spot to enjoy the magnificent Tsing Ma Bridge is the "Lantau Link Visitor Center" at the northwest end of Tsing Yi Island and the observation deck next to it. Next to the path leading to the observation deck, there stand two monuments that best symbolize the spirit of the bridge-the winding cable intercepted by the tower and the main cable. Don't underestimate these two monuments. In order to erect the main cable to support the bridge deck, we used this tower standing on both sides to form a huge cable with a diameter of 1. 1 m and a length of 1.6 million km. The length of the thin cable used is enough to go around the earth once. Looking at the explanation on the side, I really have a higher respect for the world's number one suspension bridge, and I have an admiration attitude for suspension bridges everywhere since then. Looking at the Qingma Bridge from the observation deck, we can see its majestic momentum, and its rigid steel structure symbolizes the greatness of human engineering.
2, arch bridge:
Zhao Zhouqiao, located in Zhao County, Hebei Province, was named after Zhao County was called Zhaozhou (also known as Anji Bridge) in ancient times. Zhao Zhouqiao was built during the reign of Emperor Yangdi (595-605 AD). According to Zhang's "An Ji" in the Tang Dynasty, "Zhaojun Weihe Stone Bridge is also a trace of Sui craftsmen". It has a history of nearly 1400 years. It is not only the earliest and best-preserved giant stone arch bridge in China, but also in the world. It has had a far-reaching impact on the bridge construction in the future generations of the world, especially the application of "open shoulder arch" with arch on it, which is the first time in the history of bridges in the world. In Europe, the earliest open-shouldered arch bridges are the Antony Railway Stone Arch Bridge built by French and the Dashiqiao built by Luxemburg, but it is nearly 1 100 years later than Zhao Zhouqiao in China.
Zhao Zhouqiao has a total length of 64.4 meters, a vault width of 9 meters, an arch foot width of 9.6 meters, a span of 37.02 meters and an arch vector of 7.23 meters. On the whole, it is a single-hole arc stone bridge, which is made up of 28 stone arches laid side by side vertically. Its unique architectural structure has been called "Sophia Kao is the best in the world" since ancient times. It is not only highly scientific, but also has China's unique national artistic style. This is a masterpiece of ancient architecture in China. 199 1 year, Zhao Zhouqiao was selected as the 12 "International Civil Engineering Historical Monument" by American Society of Civil Engineers, which is the only one in China at present.
3. Cable-stayed bridge:
Sutong bridge, the world's largest span cable-stayed bridge
As the world's largest span cable-stayed bridge, Sutong Bridge has set four records of the world's tallest tower, the largest pile group foundation and the longest stay cable. It is one of the modern super-large bridge projects with the highest construction standard, the most complex technology and the highest scientific and technological content in the history of bridge construction in China. Sutong Bridge, located between Nantong and Suzhou (Changshu) in the east of Jiangsu Province, is the hub project of the coastal passage from Shenyang to Haikou, a national highway planned by the Ministry of Communications. It has a total length of 32.4 kilometers and adopts the standard of two-way six-lane expressway. Among them, the main span of the main bridge is 1 088m, which can meet the navigation needs of 50,000-ton container ships and 48,000-ton fleet, and the main span of the auxiliary bridge is 268m, which can meet the navigation needs of110,000-ton ships.
