Suspension bridge, also known as suspension bridge ( suspension bridge ) refers to a bridge with cables (or steel chains) suspended through towers and anchored on both sides of the river (or at both ends of the bridge) as the main load-bearing components of the superstructure. The cable geometry is determined by the equilibrium conditions of the force and is generally close to the parabolic. Many booms are hung from the cable, the bridge deck is hoisted, and stiffener beams are often set up between the bridge deck and the boom, and a combination system is formed with the cable to reduce the deflection deformation caused by the load.
The way suspension bridges are constructed was invented in the early 19th century, and many bridges use this way of construction. Modern suspension bridges are derived from rope bridges. So far, more than 1,000 suspension bridges have been built worldwide. Today we will take a look at where the top ten suspension bridges in the world currently stand:
NO.10 Nanjing Qixiashan Yangtze River Bridge 1418 m (Jiangsu, China)
Nanjing Qixiashan Yangtze River Bridge, referred to as Qixiashan Bridge, was originally known as Nanjing Yangtze River Fourth Bridge. It is the hub project of the Shanghai-Chengdu Expressway in the main trunk line of China's "five vertical and seven horizontal" national highways and an important part of the River Crossing Passage and nanjing Ring Expressway, and is also The first three-span suspension bridge in China, ranking third in the world at that time among similar bridge types, and was known as "China's Golden Gate Bridge". However, its length has exceeded the Golden Gate Bridge
NO.9 Hangrui Expressway Dongting Lake Bridge 1480 m (Hunan, China)
HangRui Dongting Bridge is a river crossing in Yueyang City, Hunan Province, China, connecting Junshan District and Yueyang Lou District, located on the Yangtze River waterway, and is an integral part of the main urban artery in the northwest of Yueyang City. Hangrui Dongting Bridge starts from Jijiahu Road in the east, crosses the Yangtze River waterway in the upper part, and reaches Qigongling in the west; the total length of the line is 23.118 kilometers, and the length of the main bridge is 1.48 kilometers; the bridge deck is a two-way six-lane highway with a design speed of 100 kilometers per hour. Hangrui Dongting is a bridge that perfectly combines scientific and technological strength and landscape aesthetics; the outer side of the bridge tower simulates the image of "pipe pipe", full of the taste of "Xiaoxiang Qin rhyme", and also combines the humanistic characteristics of Yueyang with the natural beauty of the cave court, which can be viewed from a distance or close; the two main towers with a height of more than 200 meters go straight into the clouds, and the main cable of the bridge and the steel bridge plane are rigid and soft, and the traverse of the cave court is spectacular.
NO.8 Runyang Yangtze River Bridge 1490 m (Jiangsu, China)
Runyang Bridge, referred to as Runyang Bridge, connects Zhenjiang City and Yangzhou City, and is an important part of the main skeleton and cross-Yangtze River passage planning in Jiangsu's "four vertical, four horizontal and four links" expressway network. Jiangsu is worthy of being the leader of China's economy, and the strength of one province occupies the top twelve seats.
NO.7 Lee Sun-sung Bridge 1545m (Korea)
Historically, in order to combat the arrogance of the Japanese army and defend the territory of the motherland, Li Shunchen, a famous Korean general of the Anti-Japanese Army, was unfortunately martyred in the Battle of Luliang. In order to commemorate this great anti-Japanese general, the Korean people built this Lee Shun-sung Bridge. So that the korean descendants will never forget the heroic deeds of Lee Sun-sung.
The two ends of the Li Shunchen Bridge are Gwangyang and Lishui, and the reason for choosing this address to build the bridge is not only the need for economic transportation, but also because this is the main fierce battle area of the Luliang Naval Battle. Construction began in October 2007 and was completed and opened to traffic in February 2013, with a total length of 2,260 meters and a height of 272 meters.
In order to perfectly express people's nostalgia for General Li Shunchen and the commemoration of the Battle of Luliang, the designers also set the birth year of General Li Shunchen in 1545 as the distance between the main towers of the bridge, that is, 1545 meters.
NO.6 Ottoman Ghazi Bridge 1550m (Turkey)
The Ottoman Gazi Bridge, which crosses the Gulf of Izmit in Turkey, was completed in 2016 to bring the northern city of Qabuzé closer to the southern province of Yalova by about 140 kilometers.
NO.5 Grand Pente Bridge 1624 m (Denmark)
The Great Belt Bridge (Danish: Storebæltsbroen) is a bridge connecting the Danish islands of Zealand and Fienne, spanning the Great Penta Strait. The bridge consists of three parts, the suspension bridge (East Bridge) and the undersea tunnel between Zealand Island and Spio Island, and the Box Girder Bridge (West Bridge) from Spoo Island to Fien Island. The East Bridge is often referred to as the Grand Pente Bridge. Did you know that because the construction cost of the bridge is too high, the local government can only charge the bridge toll to the bridge crossers? This bridge became the first bridge in Denmark to charge tolls
NO.4 Xibeimen Bridge 1650 m (Zhejiang, China)
Xihoumen Bridge is a cross-sea bridge in Zhoushan City, Zhejiang Province, China, located on the Xibeimen waterway, and is one of the components of the Yongzhou Expressway (National Highway G9211) and an important part of the "Zhoushan Cross-Sea Bridge" project.
The bridge tower of Xibeimen Bridge adopts "Buddha's light yellow" as the main color, making the bridge appear solemn, auspicious, and the lines are bright and eye-catching. Under the sun, the bridge tower is dazzling. Driving on the bridge is like being shrouded in Buddha's light, as if you are really walking on the road to the Sea and Sky Buddha Kingdom.
NO.3 Nansha Bridge 1688 meters (Guangdong, China)
Nansha Bridge (Nansha Bridge), formerly known as Humen Second Bridge, is a cross-sea bridge standing between Nansha District of Guangzhou city and Shatian Town, Dongguan City, located on the Lion Ocean of the Pearl River, the western end of the Guangzhou-Longchuan Expressway; it is another world-class bridge project in the Pearl River Delta after the Hong Kong-Zhuhai-Macao Bridge.
The Dasha Waterway Bridge and the Xiaozhou Waterway Bridge also adopt the Tianyuan Local Pagoda, which fully experiences the moderate concept of rigidity and softness and balance of yin and yang. The two main bridges are light and flowing, and the style is uniform. At the same time, in order to save land, the bridge Seagull Island interchange adopts the design scheme of the ring interchange integral spiral ramp, and the upper and lower directions need to be detoured three times. Overlooked from above, the three-circled overpass resembles a beautiful and huge note.
NO.2 Wuhan Yangsigang Yangtze River Bridge 1700 meters (Wuhan, China)
Yangsigang Yangtze River Bridge, connecting Hanyang District and Wuchang District of Wuhan, is located on the Yangtze River waterway and is the tenth Yangtze River Bridge in Wuhan. It is also the world's longest double-decker suspension bridge. The upper deck is a two-way six-lane urban expressway with a design speed of 80 km/h, while the lower deck is a two-way four-lane urban main road and non-motorized road, with a design speed of 60 km/h.
NO.1 Akashi Kaikyo Bridge 1991 m (Japan)
The Akashi Kaikyo Bridge is the most important bridge on the Kobe-Awaji-Naruto route in Hyogo Prefecture, Japan, connecting Kobe City and Awaji Island. This bridge also encountered great difficulties in the construction, to know that the Akashi Strait is an international waterway, there are more than 4,000 large ships passing through the strait every day, the tide speed is extremely fast, up to 4.5 m / s, so that the direct in the water traction transition method, the use of buoyancy in the water tow transition method and the use of floating crane in the air traction transition method three kinds of lead rope erection method are difficult to apply, to the project caused a lot of difficulties. Therefore, after the study, the engineers adopted the method of using helicopters to erect guide cables, which is also the first time in the history of suspension bridge construction in the world.
After watching the top ten suspension bridges, there must be a small partner who wonders, the American Golden Gate Bridge that is bombed every day in the movie is not on the list? Isn't that supposed to be a great one? It is a pity that with the crazy road construction of China's infrastructure demon, the Golden Gate Bridge has been pitifully squeezed out of the top ten ~ I don't know if there will be a day in the future, the top ten bridges are all dominated by the Chinese bridge ~ Let's look forward to it together~
After reading the small partner, click a thumbs up and then go again~
