Who has an explanation about Jiangyin Yangtze River Bridge?

"Hibiscus City around the mountain is a strange goose nose". The beautiful Jiangyin Yangtze River Bridge Scenic Area (Ebuzui Park) is located in the northwest of Jiangyin Yangtze River Bridge Tourist Area, one kilometer away from the urban area, and is named after its winding shape like a swan extending into the river.

Covering an area of 1.280 mu, the scenic spot is dominated by mountains, with dense forests and rich night interest. The bridge scenic spot consists of three parts: Eshan scenic spot, Dawan scenic spot and Dongshan scenic spot. The majestic China No.1 suspension bridge traverses the middle of the tourist area, forming a pattern of big forests, gardens and museums with the bridge as the symbolic landscape, supporting the ancient fort and fortress forest park in Ming and Qing Dynasties, and 40 scenic spots such as Jiangweihaitou, Chengjiang Gudu, Goose Nose Snow and Rock Stream Spring. Three-dimensional tourism has become a big landscape, attracting thousands of tourists. Rotating Sightseeing Tower-75 meters high, is the highest, largest and latest high-altitude tourist facility designed and built by China. Surrounded by mountains and rivers, with the spiral rise of the cockpit, the magnificent Jiangyin Yangtze River Bridge and the new look of the ancient city are panoramic.

1, structure:

Jiangyin Yangtze River Highway Bridge is a river-crossing "throat" project of Tongjiang-Sanya national highway trunk line and Beijing-Shanghai national highway trunk line in the "two vertical and two horizontal" highway skeleton planned by the state before 2000. The bridge is located between Xishan, Jiangyin City, Jiangsu Province (under Wuxi City) and Shiwei Village, Jingjiang City (under Taizhou City). The bridge adopts a long-span steel suspension bridge across the river. The main span1385m is currently "the first in China and the fourth in the world". The south approach of the bridge 168m, and the north approach 15 18m, with a total length of 3071m.. The bridge deck is designed as a six-lane expressway with a width of 33.8 meters; The design driving speed is100 km/h; The designed throughput is 27,000 vehicles/day and the actual traffic capacity is 74,000 vehicles/day; The clear navigation height under the bridge is 50 meters, which can meet the navigation of Panama's 50,000-ton bulk carrier. The upper girder of the main bridge is a flat steel box girder, with a height of 3m and a total width of 36.9m. It needs steel1.8000 tons. The main cable consists of two galvanized high-strength steel wires with a diameter of 5.35 mm, each with more than 20,000 wires, with a total length of 17000 tons. The North Anchorage adopts a large deep well foundation with a plane size of 69m× 5 1m and a sinking of 58m, making it the largest open caisson in the world. The tower of the North-South Bridge is1.90m high, and the tower foundation adopts bored pile scheme, in which the north tower foundation consists of 96 piles with a diameter of 2m. The total investment of the bridge is 3.374 billion yuan (including 89.3 million dollars contributed by the British government).

2. Function:

1999 Jiangyin Yangtze River Highway Bridge, which was completed and opened to traffic, began to show great economic value in just three years. The industry, technology and investment in economically developed southern Jiangsu have all moved to the north bank of the Yangtze River, and the economic flood from north to south of the Yangtze River runs on the bridge deck for thousands of meters day and night. According to statistics, the average daily traffic volume of Jiangyin Bridge has increased from the initial1.2000 to the current 23000, and the cumulative traffic volume is nearly 20 million, of which 70% are freight vehicles. Jiangyin Bridge brings together two-thirds of the logistics in Jiangsu Province. Become an "integrator" of economic resources between the north and the south, and let the economy of the south of the Yangtze River cross the bridge and advance northward. Jiangyin, Zhangjiagang and Jingjiang on the north and south banks of Jiangyin Bridge are all economically strong counties in China, and Jiangyin City on the south bank has a 35km deep-water coastline of the Yangtze River. At present, more than 400,000-ton ship berths have been built, which is an important material distribution center in the lower reaches of the Yangtze River. As one of the important international trade ports in the lower reaches of the Yangtze River, Zhangjiagang has 2 1 10,000-ton berths along the 37-kilometer coastline of the Yangtze River, and its annual handling capacity exceeds150,000 tons, among which the container freight volume120,000 TEU is among the best in China. Jingjiang on the north shore, known as the "Little Jiangnan", is a virgin land, 52 kilometers along the coastline. The construction of Jiangyin Yangtze River Bridge gives it a geographical advantage similar to Jiangyin and Zhangjiagang. "Revitalizing the city with bridges" has become a new development strategic orientation of Jingjiang City.

3. Design:

Jiangyin Yangtze River Highway Bridge was awarded the first Eugene Figo Gold Award by the International Bridge Congress at the annual academic conference held in Pittsburgh. This is the first time that China has won the International Bridge Award. Eugene Figo Gold Award is named after Eugene Figo, a famous American bridge designer, in recognition of outstanding landmark bridges built around the world through imagination and innovation.
