Due to the long history, most of the Great Wall in the early dynasties was incomplete, and the Great Wall built in the Ming Dynasty was well preserved. So people usually indicate the Great Wall, and the so-called length of the Great Wall also indicates the length of the Great Wall, starting from Jiayuguan in the west and reaching Yalu River in the east.

According to the announcement, the Ming Great Wall starts from Hushan, Liaoning Province in the east and ends at Jiayuguan, Gansu Province in the west, and passes through Liaoning, Hebei, Tianjin, Beijing, Shanxi, Inner Mongolia, Shaanxi, Ningxia, Gansu and Qinghai provinces 156 counties from east to west, with a total length of 885 1.8km ... It passes through a trench of 359.7km, with a natural natural natural natural barrier of 2233.
National Cultural Heritage Administration 20/kloc-0 was announced at the Juyongguan Great Wall in Beijing on June 5th, February. After nearly five years' investigation, the total length of the Great Wall in China was 21196.18km, which was distributed in Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, Liaoning, Jilin, Heilongjiang and Shandong. This is the first time that China has scientifically and systematically measured the total length of the Great Wall. In 2009, National Cultural Heritage Administration released the survey data of the Ming Great Wall for the first time. The total length of the Ming Great Wall in China is 88,565,438+0.8km. This investigation and appraisal of the Great Wall not only identified the length of the Ming Great Wall, but also carried out the investigation of the resources of the Great Wall in Qin and Han Dynasties and other periods.

Construction method
The other side of the Great Wall-Stone Great Wall Scienc Spot (Dajingmen)
In the long history of China, many feudal dynasties built the Great Wall many times in order to consolidate their rule. Thousands of working people in ancient Qian Qian contributed their wisdom and blood, making it a miracle of the world. Whether it is a dragon-like city wall, or a production process and a more scientific brick burning workshop. Therefore, the output of brick products has greatly increased, and bricks are no longer precious building materials, so the inner and outer eaves of many places in the Great Wall of Ming Dynasty are built with giant bricks. Under the condition of manual construction and manual handling of building materials at that time, it was not only convenient to build the city wall with bricks with small weight and the same size, but also improved the construction rate and level. Secondly, the gates of many passes are long-span arches made of blue bricks. Some of these blue bricks have been severely weathered, but the whole gate is still magnificent, showing the superb skills of building arches at that time. Judging from the architectural decoration of the Guanta Tower, many stone carvings and brick carvings are extremely complicated and elaborate, reflecting the artistic talent of craftsmen at that time.
The city wall is the main part of the city wall, with an average height of 7.8 meters, and some sections are as high as 14 meters. Where the hillside is steep, buildings are relatively low.
Wan Li Great Wall (12 sheets)
Flat places are built higher; The key places are higher, and the general places are lower. The wall body is the main part of defending the enemy, with a relatively wide total thickness, a foundation width of 6.5 meters and an average floor width of 5.8 meters on the wall, so as to ensure that the two wagons run in parallel. The wall is composed of an outer eave wall and an inner eave wall, filled with soil and gravel. The cornice wall refers to the side of the skin wall facing the city. There are obvious points when building, which are generally 125% of the wall height. The separation of the wall can increase the width of the lower part of the wall, enhance the stability of the wall, strengthen its defensive performance, and make the outer wall magnificent. The inner cornice wall refers to the inner side of the outer skin wall, which is generally constructed as a vertical wall without obvious points. As for the thickness of the outer cornice wall, the thickness of the wall at the "crib" shall generally prevail. The thickness here is generally one and a half bricks wide, and it gets thicker as it goes down. Bricklaying method is mainly flat masonry.
The structural content of the wall depends on the local climate conditions. Generally speaking, the Wan Li Great Wall has the following construction methods:
1. version of rammed earth wall;
2. Adobe masonry wall;
Step 3: blue bricks
The Great Wall (20 pieces)
Build a wall;
4. Masonry wall;
5. Mixed masonry;
6. Strip stone;
7. Clay connecting brick.
Bricks, stones and masonry are used to build city walls. When the slope of the terrain is small, bricklaying or masonry is parallel to the terrain, and when the local potential slope is large, the wall is built by horizontal descent method.
Beacon and smoke
There are a large number of beacon towers as information transmission systems in the Great Wall system. In ancient times, the high platform used to light fireworks and transmit important news was an important military defense facility in ancient times, and it was the oldest but effective local telegraph. This beacon tower was built to prevent the enemy from invading. In case of enemy situation, the beacon tower smokes during the day and ignites at night, and the beacon tower is connected with the platform to transmit messages. According to historical documents, unearthed Han bamboo slips and field visits, there are a large number of beacon towers here, which extend far away from the Great Wall. According to the location and function of beacon towers, it can be divided into four groups: beacon towers located in the depths of the desert are the forefront of warning, and beacon towers set along both sides of the Great Wall transmit information along the route. A series of beacon towers from the Great Wall to the capital contacted the central government of the dynasty, and a number of beacon towers contacted local governments and garrison troops near the location of the Great Wall. According to the system of the Ming Dynasty, give a cigarette and fire a gun, which means that the enemy is about 100 people. Put two smoke bombs and two cannons to attack about 500 people; /kloc-more than 0/000 people held three cigarettes and fired three shots. Along the 50-kilometer Great Wall, * * * found more than 80 beacon towers, with an average distance of about 3 kilometers and the farthest distance of no more than 5 kilometers. "bonfire", two signals of ancient frontier warning, is called "bonfire" when smoking during the day and "flint" when making a fire at night.
Beacon towers were built earlier than the Great Wall, but since the appearance of the Great Wall, beacon towers along the Great Wall have been closely integrated with the Great Wall and become an important part of the Great Wall defense system, and some of them were even built on the Great Wall, especially in the Han Dynasty. The imperial court attached great importance to the construction of beacon towers. Beacon, also known as bonfire, is a measure of ancient military intelligence alarm, that is, when the enemy invades during the day, it burns smoke (bonfire), and when it invades at night, it ignites (bonfire) to alert all parties and superiors with visible smoke and lights. In Han Dynasty, beacon towers were called beacon towers and pavilions. In Tang and Song Dynasties, the word "beacon tower" was also extended to beacon towers. In the Ming dynasty, it was generally called a smoke pier or pier (the pier in the northwest of the Ming dynasty has the function of defending the enemy, and the small one only has the function of watching, not lighting a bonfire). Beacon towers are generally about 10 Li apart, and in the Ming Dynasty, the distance was about 5 Li. When soldiers guarding Taiwan discovered the enemy's attack, they immediately lit a bonfire on the stage, and neighboring Taiwan followed suit after seeing it, so as to quickly convey the enemy's situation to the military central department.
Geological form
"Because of the terrain, this plug is very dangerous." This is an important experience in building the Great Wall, which was affirmed by Qin Shihuang and later written by Sima Qian.
the Great Wall
In historical records, the Great Wall was built in accordance with this principle in every subsequent dynasty. All the passes in Guancheng are built between two high mountains and canyons, or at the bend of a river, or where they will pass through the plain, which can not only control the danger, but also save manpower and material resources, and achieve the effect of "one person guards it, and ten thousand people can't force it". Building castles or beacon towers in dangerous places is also an option. As for building city walls, we should make full use of the terrain. For example, Juyongguan, Badaling and other Great Walls are all built along the back of the mountain. Some sections are steep from the outside of the city wall, but very gentle inside, which has the effect of "easy to defend but difficult to attack". In Liaoning Province, the Great Wall in Liaodong Town in the Ming Dynasty had a kind of dangerous mountain wall and split mountain wall, which used steep cliffs to split the cliff slightly and became the Great Wall. Some places completely use cliffs, rivers and lakes as natural barriers, which can be said to be wonderful. As a great project, the Great Wall has become a precious heritage of the Chinese nation.
On June 25th, 20001year, the Great Wall, as an ancient building from the Spring and Autumn Period to the Ming Dynasty, was listed in the fifth batch of national key cultural relics protection units with the approval of the State Council, and it was a national 5A-level building.
