Can you please tell me how many types of bridges there are? What kind of bridges are they, such as s

There are four basic types of bridges: beam bridges, pontoon bridges, rope bridges, and arch bridges. These four types of bridges evolved according to their different building materials and construction forms:

Wooden bridges, stone bridges, brick bridges, bamboo bridges, salt bridges, ice bridges, rattan bridges, iron bridges, reed bridges, stone pillar bridges, stone pier bridges, flood bridges, outrigger bridges, covered bridges, wind and rain bridges, bamboo bridges, stone bridges, opening bridges, zipline bridges, trilateral arch bridges, pointed arch bridges, round arch bridges, even arch bridges, solid belly arch bridges, tan arch bridges, crane arch bridges, rainbow bridges, channel bridges, curved bridges, fiber road bridges, cross bridges, as well as plank roads, flying pavilions, etc., almost everything, what form of ancient bridges, can be found in our country.

According to the material: wooden bridge, stone bridge, brick bridge, concrete bridge, reinforced concrete bridge.

According to the appearance: beam bridge, arch bridge, cable-stayed bridge, suspension bridge, viaduct, combined system bridge.

According to the use: railway bridges, highway bridges, pipeline bridges, multi-purpose bridges (overpasses belong to highway bridges) according to the crossing object

A river bridge across a river A valley bridge across a valley A bridge (also known as an overpass) that crosses a railway or highway A viaduct (also known as a trestle) that crosses an urban, industrial, or crop area

According to whether the bridge can be moved, it is divided

Fixed bridges, open bridges, pontoon bridges.

According to the total length or span of the bridge, it can be divided:

Bridge, Bridge, Middle Bridge, Small Bridge.

a row of stone bridges; An arch stone bridge. Words that are usually used to denote a unit of quantity for a person, thing, or action are called quantifiers.

Quantifiers, words or morphemes used in conjunction with a noun representing a countable or measurable object, or in conjunction with a number, are often used to indicate a category to which objects assigned by a noun can be grouped according to their shape or function (e.g., "本" in the Chinese "Three Books").

There are three kinds of meanings:1. It means "each". It is basically the same as "AA". The boys are all strong.

2. It means "one by one". The overlapping form that indicates this meaning is used as an adverbial. We have to go through each piece and not miss it.

3. It means "more". He called me again and again.

No, a stone arch bridge. Arch does not do quantifiers.

Stone bridges, that is, bridges made of stone. There are stone beam bridges and stone arch bridges, both of which have a long history. Famous stone girder bridges in Chinese history include Luoyang Bridge and Lugou Bridge, which can only be used in pedestrian bridges or culverts due to their poor bending resistance.

The stone arch bridge has not only had brilliant achievements in history, but also has a high reference value in the current bridge construction.

The appearance of the stone arch bridge is beautiful, the maintenance is simple, and the local materials can be taken, especially in the area where the stone is convenient and the price is low, the stone arch bridge with a small span is built is more economical. However, the stone arch bridge is a solid heavy structure, the spanning capacity is limited, the mining, processing, masonry, etc. of the arch stone are not easy to mechanize, and the labor force required is more, and the construction period is longer, so that its development is limited to a certain extent.

The main load-bearing structure of the stone arch bridge is the arch ring. The arch structure is built with stone side walls and filled between the walls, which is called a solid belly arch bridge; The hollow arch bridge is called the hollow arch bridge with small arches added to the arch ring. The arch ring is generally built with arch stones on the arch frame with greater rigidity; There are also those that use sheet stone blocks or curved slate stones instead of arch stones.

The masonry in the arch ring should be perpendicular to the inner arc of the arch circle, and the adjacent two rows of arch stones must have staggered joints. For stone arch bridges with a span of more than 10 meters, the symmetrical masonry arch ring shall be constructed using the segmented method; The position of the segments and the order of masonry should make the force of the arch balanced and the deformation minimized. The stone arch bridge with a large span can be layered masonry because the arch ring is thicker; Build the bottom layer first, and then build the upper layer after its closure and arch are jointly loaded.

Each layer can be constructed by a combination of segmentation and reserved gaps.

No, a stone arch bridge.

Arch does not do quantifiers.

According to whether it can be moved, it is divided into fixed bridge, open bridge and pontoon bridge.

According to the structure, there are arch bridges, suspension bridges, cable-stayed bridges, and simply supported beam bridges.

Specific features: 1) Open bridge: refers to the bridge whose superstructure can be opened and closed by vertical rotation, horizontal rotation, and lifting for navigational needs.

2) Pontoon: a bridge that floats on the water with a boat or pontoon instead of a pier. The military pontoon bridge assembled by the army with standard equipment is called the boat bridge.

3) Arch bridge: It is a bridge with the arch as the main load-bearing member of the superstructure in the vertical plane. If a surface is formed in the powder layer inside the container that can withstand the pressure of the powder above without transmitting this pressure to the bottom, this surface is called an arch bridge.

The arch bridge is a curved surface that is raised upwards, and its maximum principal stress acts along the surface of the arch bridge, and the minimum principal stress along the vertical direction of the arch bridge is zero.

4) Suspension bridge, also known as suspension bridge, is composed of suspension cables, bridge towers, booms, anchor ingots, stiffening beams and bridge deck systems. The spanning capacity of the suspension bridge is the largest of the various bridge systems. According to the stiffness of the stiffening beam, the suspension bridge can be divided into two types: flexible and rigid.

5) Cable-stayed bridge: also known as diagonally tensioned bridge, is a kind of bridge that pulls the main beam directly on the bridge tower with many cables, and is a structural system that is composed of a compressed tower, a tensile cable and a bending beam. The cable-stayed bridge is composed of pylons, main beams, and cable-stayed cables.

6) Simply supported girder bridge: a girder bridge with both ends supported on a movable support and a hinged support as the main load-bearing structure. It belongs to a statically definite structure. According to the different materials used, it is divided into concrete bridge, reinforced concrete bridge, wooden bridge, stone bridge and brick bridge.

Ancient stone arch bridge. Pinyin.

Ancient stone arch bridge.

Ancient pinyin: [gǔ lǎo].

Basic explanation: It refers to a long history. Such as: ancient countries.

refers to the elderly; Old-timers. Li Bai's "Shangliutian Xing": "The ancient Xiang Yuyan, the word is Shangliutian. ”

The arched stone bridge is, can you walk?

Stone arch bridge:

Arch bridges with natural stone as the main building material have a long history, and they continue to be built in areas rich in stone history, but in a lighter direction. China's Zhaozhou Bridge is the world's oldest stone arch bridge According to the classification of structural materials, there are two kinds of bridges: stone bridges and wooden bridges, according to the number of spans, there are single spans and multi-spans, and there are arch bridges and beam bridges according to the structural type. Most of the arch bridges are stone bridges, and some are wooden structures, called stacked beam arch bridges; The beam bridge has the difference between flat beam and cantilever beam.

On the deck of all bridges, buildings such as corridors or pavilions can be built, forming a particularly beautiful image, called covered bridges. In short, there are many types of bridges to meet the different needs of different occasions.

Summary. Dear, I'm glad to answer your <>

There is a bridge, known as the first stone arch bridge in China, and the first stone arch bridge in China is the famous Zhaozhou Bridge. The Zhaozhou Bridge was built during the Sui Dynasty and has a history of more than 1,400 years, and was designed by Li Chun, a famous craftsman at that time. Zhaozhou Bridge after thousands of years of wind and frost baptism, sun and rain, after countless floods, as well as eight times of the test, still towering, Zhaozhou Bridge is strong, is incomparable to many bridges.

Kiss expansion: its shape and structure, 1, Zhaozhou Bridge bridge length meters, span meters, main arch height meters, two ends of the width of the meter, the middle is slightly narrow, 9 meters wide. 2. Because there are two small holes in the shoulders at both ends of the bridge, which are not real, it is called the open shoulder type, which is a creation of the history of bridge building in the world, and the one without a small arch is called the full shoulder or solid shoulder <>type

There is also a "frame" bridge, a "road" bridge, a "frame" bridge, and a "square" bridge.
