How to design the Yangtze River Bridge and where is the Yangtze River Bridge

Wuhan Yangtze River Bridge.

It is an important historical landmark of Wuhan City and one of the must-visit attractions in Wuhan City, Hubei Province, China, connecting Hanyang District and Wuchang District.

The Yangtze River Bridge refers to all bridges on the main stream of the Yangtze River in a broad sense, and refers to the bridges on the Yangtze River section below the mouth of the Minjiang River in Yibin, with more than 100 bridges under construction and built on the Yangtze River, 2 on the Tuotuo River, 2 on the Tongtian River, and the Jinsha River.

There are 41 bridges, 55 bridges on the Yangtze River, and 55 bridges below the Minjiang River Estuary in Yibin are all large or extra-large bridges, and the bridge names all have the word Yangtze River.

The more famous Wuhan Yangtze River Bridge, spanning the Yangtze River waterway, east to Zhongshan Road, the main bridge is 1156 meters long, and there is "the first bridge of the Yangtze River."

Reputation, construction started on September 1, 1955, and opened to traffic on October 15, 1957.

The upper deck of the bridge is a two-way four-lane urban main road, the lower layer is a double-track railroad, the idea of building the first Yangtze River bridge in Wuhan was first proposed by Zhang Zhidong, the governor of Huguang, the main purpose is to communicate the railway between the north and the south, and the Wuhan Yangtze River Bridge is also a "new democratic revolution."

Successful memorial building", Wuhan Yangtze River Bridge can be said to have poured the efforts of many predecessors, and is of great significance to Wuhan and even China.

The total length of the Yangtze River Bridge is about 6,300 meters.

There are many Yangtze River bridges in the country, and the total length of the Yangtze River Bridge is the sum of the length of these Yangtze River bridges, such as the length of the Taizhou Yangtze River Bridge, the length of the Wuhan Tianxingzhou Yangtze River Bridge, the length of the Sutong Yangtze River Bridge, and so on, the sum of the length of these bridges is about 6,300 meters.

As of November 2019, China has built 115 Yangtze River bridges of various types on the main stream of the Yangtze River, including 27 girder bridges, 57 cable-stayed bridges, 22 suspension bridges and 9 arch bridges. According to the function, there are 9 road and railway bridges, 9 railway bridges, 4 road and rail bridges, 2 pedestrian bridges, 1 pipeline bridge, and the rest are highway bridges.

The construction process of the Yangtze River Bridge

Before the founding of the People's Republic of China, there was no bridge on the Yangtze River, and the river could only be crossed by ferry, and the traffic was very inconvenient. After the founding of the People's Republic of China, on October 15, 1957, the Wuhan Yangtze River Bridge was completed and opened to traffic, and Soviet experts provided a lot of guidance for the design and construction of the bridge.

In 1968, the Nanjing Yangtze River Bridge, the first Yangtze River bridge built by China independently, was completed and opened to traffic, which is of great significance in the history of bridges in China and even in the history of bridges in the world, and is an important milestone in China's bridge construction, with great economic, political and strategic significance.

Since 1995, with the diversification of construction funds, the state has allocated a lot of money, and no bridge tolls will be charged after construction; The Yangtze River Bridges with high investment, high technology and large spans have sprung up one after another. Bridges across the Yangtze River and its larger tributaries are usually referred to as Yangtze River bridges.

1. The total length of the whole bridge is 1,670 meters, including 1,156 meters for the main bridge, 303 meters for the approach bridge on the northwest bank, and 211 meters for the approach bridge on the southeast bank. The height from the base to the road deck is 80 meters, and the lower level is a double-track railway bridge, which is one meter wide, and two trains can open at the same time.

2. The Yangtze River Bridge was built on September 1, 1955 and opened to traffic on October 15, 1957.

Wuhan Yangtze River Bridge is a river crossing channel connecting Hanyang District and Wuchang District in Wuhan City, Hubei Province, China, located on the Yangtze River waterway, is the first Yangtze River bridge built after the founding of the People's Republic of China, and is also one of the important historical landmarks in Wuhan"The first bridge of the Yangtze River"Reputation.

The construction of the Wuhan Yangtze River Bridge began on September 1, 1955; On July 1, 1957, the main bridge closure project was completed; It was opened to traffic on October 15, 1957.

Wuhan Yangtze River Bridge starts from Chuqin Interchange in the west, crosses the Yangtze River waterway in the east, and reaches Zhongshan Road in the east; The total length of the line is meters, and the main bridge is full length of meters; The upper deck is a two-way four-lane urban arterial road, with a design speed of 100 kilometers per hour, and the lower deck is a double-track railroad with a design speed of 160 kilometers per hour; The total investment amount is 100 million RMB.

The total length of the Nanjing Yangtze River Bridge is meters.

Nanjing Yangtze River Zhenkai Bridge is located between Xiaguan in Gulou District and Qiaobei in Pukou District of Nanjing, and is the first double-decker railway and highway dual-purpose bridge on the Yangtze River designed and built by China itself, which is of great significance in the history of bridges in China and the world.

Nanjing Yangtze River Bridge is a landmark building in Nanjing, a cultural symbol of Jiangsu, and the glory of China. From 1970 to 1993, it has received more than 100 countries and regions of heads of state, heads of state and more than 600 foreign delegations, and the number of domestic and foreign tourists who come here is innumerable.

The preliminary design of the Wuhan Yangtze River Bridge is to adopt the pneumatic caisson foundation that is customary in the bridge construction industry. In the Yangtze River, which is close to 40 meters deep, each worker can only work for 2 hours a day, and it is difficult to breathe, and it is very easy to have nitrogen anesthesia, and he has a kind of "caisson disease".

The former Soviet expert Xilin put forward the idea of the pipe string drilling foundation, that is, the hollow pipe string was driven into the rock face of the river bed, and the hole was drilled, and concrete was poured into the hole to make it firmly inserted in the rock, and then the cushion cap and pier body were built on it. This is a completely innovative technology. Technicians from both countries worked closely together, and after more than a year of geological surveys and painstaking experimental research, the decision was finally made to use this technology.

Because of the use of the world's most advanced construction method at that time, the Wuhan Yangtze River Bridge was originally planned to be completed in 4 years and 1 month, but it actually took only 2 years and 1 month. In the design of the Wuhan Yangtze River Bridge, the extreme environment is taken as the standard, assuming that two twin trains will pull the train, drive to the bridge in the same direction at the fastest speed, and synchronize emergency braking; At the same time, the highway bridge is fully loaded with cars, driving at the fastest speed, and there is also an emergency brake; At this time, the Yangtze River blew the largest storm, Wuhan **, and 300 tons of horizontal impulse in the river hit the bridge pier, and the Wuhan Yangtze River Bridge still needs to have enough bearing capacity.

There are two Yangtze River bridges in China, one each in Wuhan and one in Nanjing, which one is more powerful.

In Nanjing, Nanjing Yangtze River Bridge!

In Chongqing, did you know that Chongqing is the bridge capital of China? There is only a bridge type that you can't think of, and there is no bridge type that Chongqing doesn't have.
