Is the design of the Zhaozhou Bridge constructive in modern times?

The selection of the bridge site is more reasonable, so that the bridge foundation is stable and reliable. Li Chun according to his many years of rich practical experience, after strict and careful investigation, comparison, selected the first river on both sides of the relatively straight place to build the bridge, the stratum here is formed by the river alluvium, the surface of the stratum is a coarse sand layer washed by the water flow for a long time, the following is fine stone, coarse stone, fine sand and clay layer. According to modern calculations, the stratum here can withstand a pressure of 4 5 to 6 6 kg per square centimeter, while the pressure of the Zhaozhou Bridge on the ground is 5-6 kg per square centimeter, which can meet the requirements of the bridge.

After the selection of the bridge site, the foundation and abutment were built on it, and since the construction of the bridge, the foundation of the bridge has only sunk by 5 cm, indicating that the stratum here is very suitable for the construction of the bridge. <

This design in the Zhaozhou Bridge text specifically refers to: there are two small arches on each shoulder of the large arch.

The advantage of this design is that it is very sturdy and beautiful. It not only reduces the impact force of the collapsed limb of the flowing water on the bridge body, so that the bridge is not easy to be washed away by the water, but also reduces the weight of the bridge body and saves the stone.

Zhaozhou Bridge has two major characteristics: the first feature, there are no piers, there is only one arched bridge hole, and the second feature is that there are two small bridge holes on the left and right sides of the top of the bridge hole.

1.The bridge had only one large arch, which was one meter long, which was considered the longest stone arch in the world at that time. The bridge hole is not an ordinary semicircle, but resembles a bow, so that the road above the arch has no steep slopes, and the lack of trousers makes it easy for cars to get on and off.

2.The arch is made up of 28 arch circles, just like so many bows of the same shape are put together to form an arc-shaped bridge hole. Each arch ring can independently support the weight above, and if one is broken, the others will not be affected.

3.On each shoulder of the large arch, there are two small arches. This is a creative design, which not only saves stones, reduces the weight of the bridge, but also increases the amount of water passing through the bridge when the river surges, and reduces the impact of floods on the bridge.

At the same time, the arch is added to the arch, and the bridge body is also more beautiful.

4.There are also stone railings and stone slabs on both sides of the bridge, which are carved in a simple and beautiful way. Hall.

The design features of Zhaozhou Bridge make it not only practical, but also have high artistic value, and is an outstanding representative of ancient Chinese architecture.

1.In terms of the principle of the bridge: the Zhaozhou Bridge is built without piers at all, but only by the principle of arches.

2.In terms of the function of the bridge: the use of the arch in the arch to achieve drainage at high tide was a unique way to build a bridge at that time.

3.On the structure of the shell: on the left and right sides of the top of the Zhaozhou Bridge Tunnel, there are two arched small bridge holes, usually the river water flows through the bridge hole, when the big water is issued, the river water can also flow through the four small bridge holes, this design is a pioneering achievement in the history of bridge construction, reduces the impact of flowing water on the bridge body, makes the bridge not easy to be washed away by the water, and reduces the weight of the bridge body, saves the stone.

The advantages of Zhaozhou Bridge are that the arch design reduces raw materials. It reduces the impact of flowing water on the bridge body, so that the bridge is not easy to be washed away by heavy water.

Li Chun, Zhaozhou Bridge was built in the Sui Dynasty (581 618 AD) during the Great Cause (605 618 AD), designed and built by the famous craftsman Li Chun, has a history of about 1400 years, is the earliest and most well-preserved ancient open-shouldered stone arch bridge in the world today. In 1961, it was listed as the first batch of national key cultural relics protection units. Because Zhaozhou Bridge is a key cultural relic, it is easy to cause damage when it is opened to traffic, so vehicles are not allowed to pass.

There is a world-famous stone arch bridge on the river in Z County, Hebei Province, called Z National Bridge. The Hazhou Bridge, also known as the Great Bridge and the Anji Bridge, was built by the Emperor Li Chun in the sixth year of Taisho (610). Since the "coupon" is smaller than a semicircle, the "collision" is unrealistic, and the holes are parallel and are called state bridges "three bridges".

The greatest magic is the creation of an "open shoulder arch". Four small arches are arranged on the shoulders of the large arches. This not only increases the flow path and saves stones, but also reduces the weight of the bridge and increases the passive pressure of the small and small arches in the large arches.

Bridge stability. Since its construction, the Zhengzhou Bridge has more than 1,400 years of experience.

Located in a relatively flat area on both sides of the river, the bridge stone is made of hard gray-blue-gray sandstone, with a long single-hole shape, and the core of the river does not stand on the pier. The surface of the Hezhou Bridge site is a rough layer of sand formed by the influence of the current. Underneath are several layers of fine stones, coarse stones, fine sand and clay.

Each square centimeter of area can withstand the pressure of kilograms and meets the construction requirements of the Z State Bridge.

In the stone arch method, the entire bridge is laid in the direction of the bridge, and several relatively independent arch vouchers are combined side by side in the width direction. The thickness of the bow is uniform, and each hanging piece operates independently and independently; Once completely closed, create a hanging piece, move the scaffold''and create another adjacent bow that will be added to the other.

This masonry structure not only saves the wood used to make the "scaffolding", but also makes it easier to move and maintain the bridge. If the cornerstone is broken, it can be partially trimmed by embedding new stone.

Li Chun Zhaozhou Bridge, also known as Anji Bridge, is located on the river in Zhao County, Hebei Province, spans the river surface of more than 37 meters wide, because the bridge body is all built with stone, the local name is "big stone bridge". Built in 595 A.D. 605 during the Sui Dynasty, designed and built by the famous craftsman Li Chun, it has a history of more than 1,400 years, and is the second earliest existing (there is a small business bridge) in the world today, and the most complete ancient single-hole open-shoulder stone arch bridge. Zhaozhou Bridge embodies the wisdom and crystallization of the ancient working people and creates a new situation in China's bridge construction.

1] In 1961, it was listed as the first batch of national key [2] cultural relics protection units, and in 2015, it was awarded one of the top ten city business cards of Shijiazhuang. It is the first stone arch bridge in China, in the long years, although after countless floods, wind and rain, ice and snow erosion and 8 times of ** test, but safe and sound, standing majestically on the river.

The arch design of Zhaozhou Bridge is ahead of Europe for thousands of years in technology and surpasses the times.

Zhaozhou Bridge, also known as Anji Bridge, has a history of more than 1,400 years. Legend has it that it was built by Luban, the real designer is called Li Chun, and the same type of bridge we are more than 1,200 years earlier than Europe.

Zhaozhou Bridge is a stone arch bridge, which is the first case in the history of bridge construction in the world, and it is also a unique type of bridge, so its design is a pioneering achievement in the history of bridge construction.
