How was the Great Wall built?
As one of the greatest defense projects in ancient China, the construction process of the Great Wall embodies the wisdom and blood and sweat of countless working people. This article will give you a detailed analysis of the mystery of the construction of the Great Wall from four aspects: the construction background, material selection, construction methods and historical significance of the Great Wall, combined with hot topics and hot content in the past 10 days.
1. Construction background of the Great Wall
The construction of the Great Wall began during the Spring and Autumn Period and the Warring States Period, initially to resist the invasion of northern nomads. After Qin Shihuang unified the six countries, he connected the Great Walls of each country to form the original Great Wall. Since then, successive dynasties have repaired and expanded the Great Wall, among which the Ming Dynasty Great Wall was the largest.
| dynasty | Construction time | Main contributions |
|---|---|---|
| Spring and Autumn Period and Warring States Period | 7th century BC - 3rd century BC | Countries build independent Great Walls |
| Qin Dynasty | 214 BC | Connecting the Great Walls of various countries to form the Great Wall of China |
| Han Dynasty | 2nd century BC - 1st century AD | Extending westward to the Hexi Corridor |
| Ming Dynasty | 1368-1644 | Large-scale reconstruction, forming the main body of the existing Great Wall |
2. Material selection for the Great Wall
The construction materials of the Great Wall were adapted to local conditions, fully reflecting the wisdom of ancient craftsmen. Stones were mostly used in mountainous areas, while rammed earth was used in plain areas. The Great Wall of the Ming Dynasty made extensive use of masonry structures.
| Material type | Use area | Features |
|---|---|---|
| Rammed earth | Loess Plateau region | Local materials, low cost |
| stones | mountainous area | Rugged and durable |
| masonry | Great Wall of Ming Dynasty | Stable structure and strong defense |
3. Construction methods of the Great Wall
The Great Wall was built using a variety of construction techniques, the most famous of which include:
1.Rammed Earth Technology: The loess is compacted layer by layer, each layer is about 10-15 cm thick, and plant fibers such as reeds are added in the middle to enhance toughness.
2.Masonry: This method was often used in the Great Wall of the Ming Dynasty. Stones were first used to lay the foundation, then bricks were used to build the wall, and gravel and mortar were filled in the middle.
3.transportation technology: In steep mountainous areas, goats, donkeys and other livestock are used to transport materials; in flat areas, log rolling and slides are used.
| construction technology | period of use | Features |
|---|---|---|
| Rammed Earth Technology | Qin and Han Dynasties | Simple and practical, suitable for large-scale construction |
| Masonry | Ming Dynasty | Complex process and strong defense |
| transportation technology | Each period | Adapt measures to local conditions, high efficiency |
4. The historical significance of the Great Wall
The Great Wall is not only a military defense project, but also a symbol of the Chinese nation. It reflects:
