Before the bridge was completed, it took more than two hours from Zhoushan to Ningbo. I remember one time, our family of three went to Ningbo to play, and the car was facing the ferry peak when it passed Baifeng Wharf. We didn't get on the ferry from 1 until 8 pm, and it was late at night when we got home. In case of typhoon or bad weather, it is even more troublesome to refuse to cross the ship and stop. Zhoushan people can't get out, and outsiders can't get in. The vast sea is like an invisible giant wall. You see, how inconvenient it is to have no bridge!
The completion of the bridge has been a dream of Zhoushan people for thousands of years and will eventually come true! I think, by that time, our hometown will definitely undergo earth-shaking changes.
The cross-sea bridge not only connects the islands, but also connects the dreams of countless people. Let us look forward to the bridge economy era and the day when our dreams come true. Qiao Yun
What is a bridge?
Yeah! What is a bridge? Who will consider this question?
Mao Yisheng, a famous bridge scientist, once considered this question carefully. He said: "The bridge is just a bench, and there is a board on its two legs, which can bear the load. Enlarge this bench and' cross' a small river or valley to form a bridge. "
Don't! Bridge, it's not that simple No, not at all!
If so, what is a love bridge? What was the fuzzy rainbow bridge that day? So, it's not easy. There are two complicated bridges in my heart. They are-
Bridge of affection-Wannian Bridge
Time is like a filter, filtering away the dirt in memory and leaving glittering gold. I have enjoyed the simplicity and antiquity of Zhao Zhouqiao, and the vitality and grandeur of the Yangtze River Bridge. However, I always think of the small bridge in my hometown and the dream bridge in my childhood. As long as I have a holiday, constant concern always urges me to find that warm and sweet childhood memory.
This is an ancient stone arch bridge that spans Xin 'an River. The water is beautiful, the river is beautiful and the bridge is beautiful. The bluestone road on the bridge has been polished by the feet of pedestrians.
This bridge has added gorgeous colors to my interesting childhood. However, the wheel of life took away my childhood and innocence when I transferred, moved, moved to high school and lived in school. When I walked to the bridge again, the cheerful and calm feeling of the lake could not help but cause a melancholy ripple.
Listen, there is the sound of running water like a piano under the bridge. It is Taiping Bridge, a bridge full of my childhood and affection.
Bridge of Friendship-Wannian Bridge
It's raining outside the window, and my thoughts are soaked. Winter has gone, a ray of spring brings warmth, and the bridge in my hometown is connected with unforgettable friendship.
Remember that old bridge? I remember, we remember, we are a group of laughing children, a group of young and naive partners, and a group of classmates who get along with each other day and night. We have walked together, with sincerity, hope and dreams, through the ancient bridge in the wind and rain and the ancient bridge in the sun.
A few mosses, a few grasses, or a few small snails leisurely show the richness and tranquility of this bridge. Walking through the bluestone road polished by predecessors, the sound is empty, which is the echo of the collision between reality and history. ...
The scientific name of the ancient bridge is Wannian Bridge, and I call her Friendship Bridge. It accompanied us through the innocent, innocent and beautiful flower season.
The ancient Huizhou culture has made you, the uneven archway holds you up, the soft smoke from the kitchen covers you, and two affectionate eyes miss you. Ah! The bridge of affection-the bridge of friendship, pure color, vigorous and elegant posture, is a spring breeze on my life, a touch of sunshine ... Tower Bridge in London.
A bridge over the Thames in London, England, and the first bridge since the Thames entered the sea. Built in 1886- 1894. There is a tower at each end. The middle section is 60 meters long and divided into upper and lower floors. The lower bridge truss can be opened upwards for ships to pass through; Pedestrians cross the bridge from the upper deck, which is about 42 meters above the high tide level.
Tower bridge is a suspension bridge, originally a wooden bridge, later changed to a stone bridge, and now it is a cement structure bridge with six lanes. The foundations of the two bridges in the river are 7.6 meters high. There are two main towers on the bridge foundation, which are square five-story towers made of granite and steel, and the height is more than 40 meters. The two main towers are made of white marble roofs and five small minarets, which look like two crowns from a distance. The span between the two towers is more than 60 meters, and the tower foundation and the two banks are connected by cable suspension bridges. The bridge is divided into upper and lower floors. The upper floor is a wide suspended sidewalk with glass windows on both sides. Pedestrians can enjoy the beautiful scenery on both sides of the Thames when they pass the bridge. The lower floor is accessible to vehicles. When the 10,000-ton ship crossed the Thames, the machines in the main tower started and the bridge slowly separated and folded. After the ship passed, the bridge body slowly fell and the traffic resumed. Two movable bridge decks, each weighing1000t. Looking at the tower bridge from a distance, the Twin Towers are majestic. If the bridge is locked by mist, the landscape will be more unique; The fog lock tower bridge is one of the attractions in London.
From the bridge or the river, you can see that the British warship Belfast is parked on the river not far away. This is the most intact warship in Britain since World War II. The Zhaozhou Bridge
Zhao Zhouqiao, also known as "Anji Bridge", is located about 40 kilometers southeast of Shijiazhuang and 2.5 kilometers south of Zhaoxian. It spans the north and south banks of Lianshui, and was built from the first year to the eleventh year of Sui Daye (605-6 16) and supervised by craftsman Li Chun. It has a history of 1300 years. Because the bridge body is made of stone, it is commonly known as "Dashiqiao".
Zhao Zhouqiao has a novel structure and beautiful appearance, with a total length of 50.82 meters, a width of 9.6 meters and a span of 37.37 meters. It is a single-hole arch bridge composed of 28 independent arches. There are two small circular arches on the left and right sides of the bridge top, which are used to speed up flood discharge, reduce the weight of the bridge body and save stone. This is a pioneering work in the history of bridge construction. The guardrail posts on both sides of the bridge deck are carved with various exquisite patterns, with vigorous knives and vivid shapes. Structurally, the curved flat arch and the small arch with shoulders give people a sense of movement that is big and light and eager to fly. The lines are both rigid and soft, lighter than hidden, and meaningful and magnificent. On the main vault, there is a Longmen stone carved with a faucet, and the side of the bridge is dotted with a face stone of eight petals lotus. These statues convey the hope that the bridge will not be destroyed by water and will exist forever. Zhao Zhouqiao occupies a very important position in the history of bridges at home and abroad, and has a far-reaching influence on the bridge architecture in China.
Zhao Zhouqiao's greatest scientific contribution is to create an "open-shouldered arch", which is the first time in the history of bridges in the world. Four parallel small holes are built on the two shoulders of the big arch, which not only increases the water passage, saves the stone and reduces the weight of the bridge, but also facilitates the passive pressure of the small arch on the big arch and enhances the stability of the bridge. This has effectively ensured that Anji Bridge has withstood numerous floods, eight major earthquakes and the heavy weight of vehicles in the history of 1400 years, and still stands upright on the river.
The application of Zhao Zhouqiao's "open-shouldered arch" is the first time in the world bridge history. 1883, Antoinette railway bridge built by France on Argo River started the construction of long-span open-shouldered arch bridge in Europe, but it was later than Anji Bridge 1400 years ago. Western scholars admit that the open-shouldered arch building of Anji Bridge has become the ancestor of many modern reinforced concrete bridges, which has opened a generation of bridge style.
Zhao Zhouqiao is known as "the first bridge in the world" and "the miracle of the world" for its extraordinary characteristics. 196 1 on March 4th, Zhao Zhouqiao was announced by the people of China and the State Council as the first batch of national key cultural relics protection units. On September 4th, 199 1 was selected as the12nd "International Civil Engineering Milestone" by American Society of Civil Engineers. On the east side of the north end of the bridge, there is a bronze medal monument of "International Civil Engineering Historical Monument", which is famous far and wide.
Zhao Zhouqiao is another treasure of architectural art, which spans the river like a rainbow and is magnificent. On the arc-shaped flat main arch line, there are four small arches lying symmetrically, like four huge jade rings, dotted on the two shoulders of the bridge. The giant body is ethereal and the lines are bright. In the grandeur, it reveals a magnificent and light aesthetic feeling. An imaginary water-absorbing beast was created at the top of the bridge, which placed people's good wishes that the bridge would not be damaged by water and exist for a long time. All kinds of dragons, animal faces, flower ornaments, bamboo joints, etc. There are carvings on fences and sentries, among which dragons are the most exquisite. The dragon is either entrenched in the game or landed in the water, unpredictable and its expression is extremely moving. The carving method is vigorous and powerful, and the artistic style is novel and bold. 199 1 year, the American Society of Civil Engineers selected Zhao Zhouqiao, China as the 12 civil engineering milestone in international history, which added new glory to the stone arch bridge in China.
Zhao Zhouqiao was built in the great cause of the Sui Dynasty (605 ~ 6 16), designed and built by the famous craftsman Li Chun. It is the oldest open-shouldered stone arch bridge in the world. The main arch of Zhao Zhouqiao is composed of 28 arch pieces, with a length of 64.40 meters and a span of 37.02 meters. Four symmetrical small arches are added to the back of the main arch. This bridge construction method not only saves materials and reduces the dead weight of the bridge, but also increases the drainage flow of the river under the bridge and weakens the influence on the bridge. Adding an arch to the arch makes the bridge look exquisite and beautiful, which is indeed an epoch-making initiative in the history of bridge construction in the world.
Ancient Zhao Zhouqiao (also known as Anji Bridge), which "swallowed Zhao", is located in the throat of military strategists. Pedestrians and horses with rafts on their shoulders worked day and night. In addition, earthquakes and wars have repeatedly destroyed it. Since the Tang Dynasty, it has been restored eight times. The Zhao Zhouqiao we are seeing now is a comprehensive renovation from 1953 to 1958 after the founding of New China, which is also the largest restoration project since the bridge was built 300 years ago.
/kloc-for more than 0/000 years, it has won the world's amazement with its peculiar architectural art. Zhang, a minister in the Tang Dynasty, exclaimed in the inscription of Dashiqiao that "nature is strange and people don't know why". Liang Sicheng, a famous modern ancient architect, said that the structure of Zhao Zhouqiao "adopts a way of knowing engineering mechanics very well and extremely economical and intelligent control. ..... showing a very modern and progressive engineering spirit, which is amazing. " 199 1 year, American society of civil engineers selected Zhao Zhouqiao as "International Civil Engineering Historical Monument".
Visitors can browse on foot on the tower bridge for free. When visiting Tower Bridge, you can take the elevator from the tower bridge in the north to watch the structural engineering of the bridge, and then walk across the Thames from the high-altitude passage of the bridge to enjoy the beautiful scenery of the Thames and its banks. There is an exhibition room in the tower to learn about the history and work of the bridge. At Westminster Bridge (behind Parliament Building), there is a tour of the Thames (Parliament Building-Tower Bridge) co-organized by cruise companies every day. The journey is near 1 hour, and the ship fee is about 8 pounds. Visiting the Tower Bridge Museum in London and the Belfast warship is charged and not cheap.
London Bridge
London Bridge: In the past, this rock was a promontory, highlighting the connection between the sea and the land. Due to the scouring and erosion of the waves, two round holes were formed, which just formed a double arch, hence the name "London Bridge". 1990 65438+1October 15 In the evening, the circular hole connected with the land suddenly collapsed and separated from the mainland, forming the broken bridge we see now. The power of nature is enormous, and the landscape shaped by nature has unparalleled magic!
To put it bluntly, London Bridge is a natural product, and London Tower Bridge is an artificial masterpiece.
