Zhaozhou Bridge is in Zhao County, Shijiazhuang City, Hebei Province.

The Zhaozhou Bridge, which enjoys the reputation of "the first bridge in the world", is located on the Hu River in Zhao County. Built in the Sui Dynasty, designed and built by the famous craftsman Li Chun, it has a history of about 1,400 years, and is the earliest and most well-preserved ancient open-shouldered stone arch bridge in the world. In 1961, it was listed as the first batch of national key cultural relics protection units.

Zhaozhou Bridge has a unique construction technology, and is the first "open shoulder arch" structural form in the history of bridges in the world, which has high scientific research value; The carving knife technique is vigorous and powerful, the artistic style is novel and bold, showing the vigorous, strict and handsome stone carving style of the Sui Dynasty, and the bridge body decoration is finely carved, and has high artistic value.

Structural features:

1. Open-shouldered arc arch: two symmetrical small arches are built on each of the two spandrels, which lie on the shoulders of the main arch. In line with the principle of structural mechanics, increase the drainage area and save stones.

Second, the span is large, the arc is flat: the form of a single hole long span is adopted, and the bridge pier is not erected in the center of the river; In the form of a circular arch, the height of the stone arch is reduced. It is better than the characteristics of small single-span span and many piers of the Duokongsen slip bridge, which is not conducive to flood discharge.

3. The two ends are wide and the middle is narrow.

Fourth, longitudinal parallel masonry method.

Zhaozhou Bridge, also known as Anzi Zhiji Bridge, is located in the suburbs of Zhaoxian City, Hebei Province, on the river, it is the world's earliest and best-preserved huge stone arch bridge, has a history of more than 1400 years, and is known as "one of the four treasures of North China". It was built during the reign of the Sui Dynasty (605-618 AD) and was built by the famous craftsman Li Chun. The bridge is long and spans meters, and it is the world's largest span and the earliest single-hole open-shoulder stone arch bridge.

Because there are two small holes in the shoulders at both ends of the bridge, which are not solid, it is called the open shoulder type, which is a creation of the history of bridge building in the world (the one without a small arch is called the full shoulder or solid shoulder type).

Zhaozhou Bridge has been built 1400 years ago, experienced 10 floods, 8 wars and many times, especially in 1966 Xingtai occurred in the level **, Xingtai is more than 40 kilometers away from here, there are also four points here **, Zhaozhou Bridge has not been damaged, the famous bridge expert Mao Yisheng said, regardless of the internal structure of the bridge, just that it can exist for more than 1300 years to explain everything. The flood of 1963 flooded the dragon's mouth of the arch of the bridge, and according to local elders, you can feel the bridge shaking a lot when you stand on the bridge. According to records, the Zhaozhou Bridge has been repaired 8 times since its completion.

Two small arches are added at both ends of the main arch coupon, one is to save materials, the other is to reduce the weight of the bridge body (reduce the weight by 15%), and can increase the discharge volume of the river under the bridge.

In May 1979, a joint investigation team was formed by four units including the Natural History Group of the Chinese Academy of Sciences to investigate the foundation of the Zhaozhou Bridge, which weighed 2,800 tons, and its foundation was only a five-layer stone abutment built into a high meter, which was built directly on the natural sand and gravel.

Such a shallow foundation is unbelievable, and when Mr. Liang Sicheng visited it in 1933, he thought that it was only a diamond wall for waterproofing, and not a foundation that could accommodate the entire load of the bridge. He wrote in the report:

In order to measure the coupon base, we excavated at the foot of the coupon on the north side of the calendar, but about 70-80 cm below the current riverbed, we found a flat stone wall under the coupon. There are five layers of stone, a total height of meters, each layer is slightly higher than the upper layer, and there is no solid foundation below, which is clearly only a diamond wall used for waterproof flow scouring, but not the foundation that accepts all the load of the bridge ticket. Because the water will be visible at another 30-40 cm, unless there is a large-scale excavation, it is impossible to reach the location of the large bridge foundation that we have speculated according to our theory.

In September 1991, the Zhaozhou Bridge was selected by the American Society of Civil Engineers as the twelfth "International Civil Engineering Milestone", and the "International Civil Engineering History" was built on the east side of the north end of the bridge.

Zhaozhou Bridge is on the South Hu River in Zhao County, Shijiazhuang City, Hebei Province.

Zhaozhou Bridge is a stone arch bridge located on the south of Zhao County, Shijiazhuang City, Hebei Province, named after Zhao County's ancient name of Zhaozhou. Locals call it the Big Stone Bridge to distinguish it from the Yongtong Bridge (Small Stone Bridge) outside the west gate of the city. Zhaozhou Bridge was built in the Sui Dynasty, designed and built by the craftsman Li Chun, and later named Anji Bridge by Zhao Xu, the late Emperor of Song Zhezong, and took it as the proper name.

Zhaozhou Bridge is the world's oldest existing single-hole open-shoulder stone arch bridge with the largest span and the most complete preservation, and its construction technology is unique, and it is the first "open-shoulder arch" structural form in the history of bridges in the world, which has high scientific research value; The carving knife technique is vigorous and powerful, the artistic style is novel and bold, showing the vigorous, strict and handsome stone carving style of the Sui Dynasty, and the bridge body decoration carving is fine and difficult, and has high artistic value. Zhaozhou Bridge occupies an important position in the history of bridge building in China and has a profound impact on bridge construction for future generations around the world.

Zhaozhou Bridge is located in the south of Zhao County, Hebei Province, on the Huhe River, because Zhao County was called Zhaozhou in ancient times, so it was named Zhaozhou Bridge, and because the bridge is made of stone, so it is commonly known as the big stone bridge.

Zhaozhou Bridge (Zhaozhou Bridge), also known as Anji Bridge, commonly known as the Big Stone Bridge, is a stone arch bridge across the Zhaoxian River in Zhao County, Shijiazhuang City, Hebei Province, China, built by Li Chun, a craftsman of the Sui Dynasty, and is the world's oldest existing single-hole open-shoulder stone arch bridge with the largest span and the most complete preservation.

Zhaozhou Bridge is located in Shijiazhuang, Hebei Province.

Zhaozhou Bridge is in Zhao County in Shijiazhuang, because the ancient name of Zhao County is Zhaozhou, so it gets this name. The local people like to call it the Great Stone Bridge, and the Zhaozhou Bridge was built in the Sui Dynasty and was designed and built by Li Chun. Later, Zhao Xu of Song Zhezong gave the name Anji Bridge, and took it as the only imitation of the correct name.

Zhaozhou Bridge is the world's oldest, largest span, the most well-preserved single-hole arc open-shoulder stone arch bridge, and its production process is very unique. In the history of bridges in the world, it is the first to create the "open shoulder arch" structural form, which has high scientific research value. The artistic style of Zhaozhou Bridge is novel and bold, which also shows the vigorous and strict stone carving style of the Sui Dynasty.

Introduction to Zhaozhou Bridge

Zhaozhou Bridge was built in the Sui Dynasty and was designed and built by the craftsman Li Chun, with a history of more than 1,400 years. In 1958, the repair project of Zhaozhou Bridge was completed, which was the eighth repair of Zhaozhou Bridge. The repair of the Zhaozhou Bridge was comprehensively measured and repaired, and the whole project adopted the original five methods of dusty mountain key arch protection stone, hook stone, waist iron, iron tie rod and collection.

In addition, two sticky and three oil waterproof layers (two layers of waterproof linen and three layers of asphalt) are added above and below the bridge deck to prevent water leakage and corrosion. All the railings on the bridge deck were newly made according to the early style.

The reasonable location of the Zhaozhou Bridge is an important reason why it has become a thousand-year-old bridge, and Li Chun chose the foundation site of the Zhaozhou Bridge in the coarse sand of the Huhe River, because the coarse sand as the foundation can improve the load-bearing strength of the bridge to ensure the stability of the bridge. Modern surveys show that the stratigraphic distribution of the bridge site area of Zhaozhou Bridge is stable. The foundation soil is mainly dense silty clay, with silt and sand interlayer in the middle, which is an ideal place for building this kind of extra-large span single-hole bridge.
