Zhaozhou Bridge is also known as Anji Bridge, which is now known as the ancient [open shoulder arch stone bridge Zhaozhou Bridge].It was built during the reign of the Sui Dynasty (605-618 AD) and was built by the famous craftsman Li Chun.

Guangji Bridge, commonly known as Xiangzi Bridge, [the earliest switch movable stone bridge] Song Qiandao seven years (1171) Taishou Zeng River was founded, the beginning of the pontoon bridge, by 86 giant ships connected to form the original name of "Kangji Bridge". There is also such an explanation that Xuande was built in the tenth year (1435).

The earliest existing bridge is also the most bridged and the most [the arch stone bridge is Suzhou Baodai Bridge in Jiangsu]. It was built in the eleventh year of Tang Yuanhe (816).

The earliest existing cross bridge is Shanxi Jin Temple Yunuma Feiliang, built in the first year of Chongning in the Northern Song Dynasty (1102).

The bridge is an overhead man-made passage, which is composed of three parts: the superstructure, the lower knot and the foundation. The superstructure comprises the bridge body and the bridge deck, and the substructure comprises the pier and the abutment, and the foundation is composed of an open-cut foundation, a pile foundation, a caisson foundation, a caisson foundation, a pipe string foundation and a cushion cap.

A bridge is a large structure used to cross an obstacle, a structure that crosses a natural or artificial obstacle for a transportation route or other facility to allow a person, vehicle, train, or ship to pass through the obstacle.

The orange bridge is divided according to the rapid point of the special round cluster, there are five basic types of beam bridges, arch bridges, rigid frame bridges, suspension bridges, and composite system bridges, and the bridge is generally built in a very large span, the water area is shallow, and is composed of bridge columns and bridge plates.

Arch bridges are generally built on water areas with smaller spans, and the bridge body is arched, and there are generally several bridge holes, which play the function of flood discharge, and the weight in the middle of the bridge is transmitted to both ends of the bridge, and the weight at both ends is transmitted to the middle.

A bridge is a large structure used to cross obstacles. Specifically, it is a structure used to cross transportation routes (such as roads, railways, waterways, etc.) or other facilities (such as pipelines, cables, etc.) over natural obstacles (such as rivers, straits, canyons, etc.) or artificial obstacles (highways, railway lines). The purpose of a bridge is to allow people, vehicles, trains, or ships to pass through the barrier.

The bridge can be built on both sides of a river valley or strait, or it can be raised above the ground and cross the river or road below, allowing traffic to flow smoothly below. The "bridge" was originally a tall tree (see arbor), because it was tall enough to be cut down and placed long enough on the surface of the river, and could be connected to two banks, that is, a single-plank bridge.

The bridge is generally composed of a superstructure, a substructure, a bearing and an ancillary structure, and the superstructure, also known as the bridge span structure, is the main structure for crossing obstacles; The substructure comprises abutments, piers and foundations; The bearing is a force transmission device that is arranged at the supporting place of bridge span structure and bridge pier or abutment; Ancillary structures refer to bridgehead laps, tapered slope protection, bank revetments, diversion projects, etc.

The bridge is generally composed of five major components and five small parts, and the five major components refer to the bridge span superstructure and substructure that bear the transportation load of automobiles or other vehicles, which is the guarantee of the safety of the bridge structure. Includes:

1. Bridge span structure (or bridge hole structure. superstructure),

2. Bridge bearing system

3. Bridge piers and abutments.

4. a cushion cap. 5. Dig wells or pile foundations.

The five widgets refer to those that are directly related to the service function of the bridge, which used to be called bridge deck construction. Includes:

1. Bridge deck pavement

2. Anti-drainage system

3, railing, 4, expansion joint

5. Lighting, large bridge ancillary structures, bridgeheads, approach bridges and other settings.

1 The most ancient Chinese bridge.

The oldest existing open-shouldered arch stone bridge is the Zhaozhou Bridge in Zhao County, Hebei Province. It was built from the fifteenth year of the opening of the Sui Dynasty to the first year of the Great Cause (595 605).

The earliest existing bridge is also the most bridged and the most [the arch stone bridge is Suzhou Baodai Bridge in Jiangsu]. It was built in the eleventh year of Tang Yuanhe (816).

The earliest existing cross bridge is Shanxi Jin Temple Yunuma Feiliang, built in the first year of Chongning in the Northern Song Dynasty (1102).

The earliest switch-movable large stone bridge is Guangji Bridge in Chaozhou, Guangzhou. It was built in the tenth year of Xuande in the Ming Dynasty (1435).

The only Wuting Bridge is located in Slender West Lake in Yangzhou, Jiangsu.

2 Interchanges add a modern touch to the city. The earliest road overpasses built in Beijing are the Baiponhe Bridge on Changping Road, the Balizhuang Bridge on Landichang Road and the Lane Ditch Bridge, all of which were completed in 1966. In 1974, the first alfalfa leaf-shaped interchange was built in the urban area - Fuxingmen Bridge.

Siyuan Bridge is located at the intersection of Capital Airport Expressway, Jingshun Road and Fourth Ring Road, which is a four-layer fully interconnected large-scale overpass, with a total of 26 large and small bridges and a total length of kilometers, which is the largest urban overpass in the country. Located at the intersection of South Second Ring Road and Dongpu Road, Jade Fly Bridge is a three-storey interchange dragonfly-shaped overpass.

3 The construction of undersea tunnels is costly and long, so people are more likely to choose sea-crossing bridges. At present, there are more than 30 large sea-crossing bridges in the world. The 25-kilometre-long Bahrain-Saudi Arabia Bridge on the Persian Gulf is the longest bridge in the world today.

The Messina Bridge in Italy connects the boot-shaped mainland with the football-shaped island of Sicily. Although the Bosphorus Bridge in Istanbul, Turkey, has a span of only 1,560 meters, it is an intercontinental bridge over Europe and Asia.

3. Ten rules of bridge beauty (Fan Fan).

Regarding the beauty of bridges, many people have long been concerned, and have put forward a lot of ideas and measures, about the beauty of bridges morphological laws, aesthetic standards, etc., from some literature to disclose their views, classification is more inconsistent, it can be said that there are different opinions. Referring to these materials, and combined with some principles used in bridge engineering in China, the following ten bridge beauty rules are drawn up in a simple and clear form, and bridge examples are listed and discussed separately. These ten are:

1. Coordination of the environment; 2. Master-slave and symmetry; 3. Rhythm; 4. Balance and stability; 5. Unification; 6. Proportion and scale; 7. Continuous and light and dark collocation; 8. The line of force is bright; 9. Color; 10. Style. These laws can also be said to be the laws of "coordination".

A bridge is a large structure used to cross obstacles, more precisely to cross transportation routes or other facilities over natural obstacles. The purpose of the bridge is to allow the ...... of people, vehicles, trainsWalk through the obstacles. Bridges are classified as highway bridges, road and rail bridges, pedestrian bridges, machine farming bridges, and water bridges.

A bridge is an overhead man-made passageway. It is composed of two parts: the superstructure and the substructure. The superstructure includes the bridge body and deck; The substructure consists of piers, abutments, and foundations.

They hang high and lie low, with thousands of forms, some of them are male and far away from the mountains and mountains, simple and elegant; Some cross the rocky ravines and streams, and the mountains and rivers increase their brilliance; Some are located in the thoroughfare of the downtown area, with strange shapes; Some bridges are multi-purpose, ingenious. Regardless of the wind and rain, no matter the scorching heat and severe winter, they always cross the river for the majority of pedestrians, chariots and horses, and fly to cross.

According to historical data and investigation, in the primitive society, there was a single-plank bridge and a wooden beam bridge made of several logs in China. As early as the Warring States Period, single-span and multi-span wooden and stone beam bridges were commonly built in the Yellow River Valley and other regions. The Blue Bridge, which was built on the Lanyu Water in Lantian County, Shaanxi Province more than 300 years BC, is a representative of the multi-span wooden beam and wooden pillar bridge.

The Book of Poetry, Daya, and Ming Dynasty for the first time describes that King Wen of Zhou married his wife and built a pontoon bridge on the Wei River for the emperor. Nearly 20 pontoon bridges have been set up on the Yangtze River and the Yellow River. The first pontoon bridge over the Yellow River was built near the Jin Pass in 541 B.C., and was built by the mother and younger son of Qin Jinggong, who was afraid of being killed by Jinggong and fled to the Jin Kingdom by car.

The first Yangtze River pontoon bridge was built by Emperor Guangwu of the Eastern Han Dynasty in 35 AD, and the bridge site was on the river between Yichang and Yidu.

The suspension bridge was first created in China, and the sling developed from rattan rope and bamboo cable to iron chain. In the middle of the Tang Dynasty, there were chain suspension bridges, more than 800 years earlier than in the West. The arch bridge was built in the middle of the Eastern Han Dynasty, and its many forms and beautiful shapes are rare in the world.

Baqiao, Luoyang Bridge, Anping Bridge, Hudu Bridge, Shaoxing Bazi Bridge, Yinping Bridge, Chengyang Bridge, etc. are representatives of wooden and stone beam bridges. Xi'an Baqiao was built in the Han Dynasty, is a wooden beam stone pillar pier bridge, it uses four sections of circular stone pillars and tenons to connect (in the middle also adds stone pillars) to form a stone pillar, by six stone pillars to form a light bridge pier, the pier platform is added with wooden beams and laid gray earth stone slab bridge deck. It is the originator of the stone pillar pier.
