Wuhan, China, the world bridge culture.

Speaking of the Yangtze River Bridge, those citizens born and raised in Wuhan must have different feelings and feelings about this bridge. The completion of Wuhan-Wuhan Yangtze River Bridge not only makes the natural barrier a thoroughfare, integrates the three towns and runs through the north-south artery of China, but also realizes the dream of China people for thousands of years and glows the enthusiasm of China people for building a new life. So it touched people's hearts and touched the feelings of hundreds of millions of people.

Since the formal confirmation of the bridge construction, the people of the whole country have paid great attention to and supported the bridge construction with great enthusiasm, and all walks of life have lent a helping hand. Grandma Wang, who lives in Hanyang, recalled that it was really hot then. Millions of Wuhan citizens rushed to participate in voluntary labor, and all men, women and children were sent free of charge. Many people pry up the good stone slabs in front of and behind their houses and donate them to pave the way and bridge. During that period, many children born in Wuhan were named "Bridge", "Building Bridge", "Han Bridge", "One Bridge" and "Wuqiao" in unison, thus making this magnificent building accompany them all their lives.

Yu Qixin, deputy chief economist of China Railway Bridge Bureau, said that at that time, at the Jianqiao Xincun police station, all the people who came to register newborns were called "Jianqiao". The staff of the police station advised: "There are too many people by this name, please change it!" "Then call it' Hanqiao'!" "But there are many people called Hanqiao. Let's change the name! " Although persuaded by the comrades of the police station, 25 babies born in that area in those two years were named "Jianqiao" and 15 was named "Hanqiao".

At that time, many products produced in Wuhan also took "Bridge" as their own brands, such as Bridge cigarettes, Bridge monosodium glutamate, Bridge baby carriages, Bridge sewing machines, Bridge toothbrushes, Bridge shirts ... When you open the old photo albums of each family, I'm afraid there will inevitably be photos with the bridge as the background.

In the spring and autumn of 50 years, the piers and steel beams of the Yangtze River Bridge have been hit by ships for more than 70 times, and the number of times the piers have been hit is the highest in China, but the operation has not been affected, fully demonstrating its intact quality. Especially 1983 and 1998, there are high flood levels in Wuhan. In recent two years, the highest water level, maximum discharge and fastest flow rate all exceeded the historical record, and the flood peak exceeded 10 times, and the bridge was washed for more than 12 hours each time, so the bridge was firm.

In the past 50 years, the bridge has been inspected by the bridge management department for many times, and the static load, dynamic load and seismic performance have been tested experimentally. The results show that the whole bridge has no displacement and settlement, and the pier can still bear 60,000 tons of pressure, and it still has the ability to resist the flow of 654.38+ million cubic meters per second and the rapid water breakthrough of 5 meters per second, and it can still resist earthquakes and strong collisions below magnitude 8. By the end of the project, there were no cracks, bending deformation and rivet looseness in the 24,805-ton steel beam and eight piers of the bridge.

Many bridge and railway experts in China confirmed that this bridge is "young" and properly maintained. The steel beam of the bridge can be over 100 years, and the pier can be used for 200 years. According to Academician Fang Qinhan, a bridge expert, the planning when building a bridge is a "century-long plan". Apart from a little "skin disease"-the steel beam is a little rusty, the paint is a little peeling off, and there is a little "rheumatism"-the expansion of steel bars has burst the concrete shell, and there is nothing wrong with the bridge.

At that time, based on the extreme environment, the design of the bridge was ahead of schedule: suppose that two trains are pulled by two engines and travel to the center of the bridge at the fastest speed in the same direction, and synchronize emergency braking; At the same time, the highway bridge was full of cars, driving at the fastest speed, and there was an emergency brake. "More unfortunately," at this time, the biggest storm blew on the Yangtze River, and an earthquake occurred in Wuhan. The horizontal impact force of 300 tons in the river hit the pier, and the Wuhan Yangtze River Bridge remained rock-solid.

Experts from Wuhan Railway Bureau said that the bridge design has enough safety reserves. Up to now, the railway bridge still has surplus capacity and is not fully loaded. Today, Wuhan Yangtze River Bridge has become a "benchmark" of a bridge, a high-quality model bridge. The Bridge Bureau is proud of the high quality of this bridge, and it has also had a demonstration effect on other bridges.

The Yangtze River Bridge is only an achievement of new China, but it reflects the culture of an era, that is, the cultural characteristics of the Mao Zedong era. We need to know history, and only by knowing it deeply can we be qualified to evaluate it. This is especially true of history and culture.
