Throughout the ages, we have been unable to surpass the wisdom and art of the ancients. Although we have a powerful technological system, the copied products are far from comparable to the buildings and works of art made by the ancients.
Like the Forbidden City we are familiar with, its internal structure is far beyond our imagination. Do you still remember the Tangshan earthquake?? At that time, the epicenter of the earthquake was only 150 kilometers away from the Forbidden City. Most of the ancient buildings in the capital were damaged during the earthquake, but the Forbidden City has remained standing.
Why does the Forbidden City remain standing? Is there hidden technology or the wisdom of the ancients?
In order to clarify these problems, British craftsmen made a replica of the Forbidden City at a scale of 1:5 in 2017, and then the staff put it into a device that simulated earthquakes. The purpose was also to detect these How long can ancient buildings last?
At the beginning, they chose the medium-strong mode, which is the 4.5 magnitude mode. An earthquake of magnitude 4.5 is enough to make people feel obvious shaking, and even cause some buildings that cut corners to collapse.
Time flies. After a period of simulation, although the Forbidden City model has been swaying, what I didn't expect is that the model will remain standing for a long time.
Although it did not collapse under the test of a 4.5-magnitude earthquake, the engineer said at this time that the 4.5-magnitude earthquake shook so badly that it would definitely collapse in a 6-magnitude earthquake. At this time, the Chinese experts on the scene smiled knowingly.
Subsequently, engineers adjusted the magnitude to level 6, but a surprising scene appeared. It still did not let us down. After a long period of testing, it is still standing.
Since it doesn't fall down, let's go straight to magnitude 7.5. You must know that an earthquake of magnitude 7.5 is already a major earthquake. When it is severe, humans cannot stand. But what scientists didn't expect was that although the internal walls collapsed, the overall wooden structure remained strong.
Okay! Since it doesn't fall down, just fill it up directly. I will directly modulate it to level 10. You know, a magnitude 10 earthquake is already the largest earthquake at present, but 30 seconds later, this building silenced the foreigners in the audience. Although the model shook greatly, it did not collapse in the end. After many test results of
, foreigners have to admire China's infrastructure, it is really too strong. But at this time, foreigners began to be curious, why can it withstand a magnitude 10 earthquake?
Actually, this is related to the construction method used by ancient people. When we build buildings today, we usually drive the foundation pillars directly into the ground. However, although this method looks strong, it will be destroyed immediately in the event of an earthquake.
However, the ancient construction method used core technologies such as piers and pans to control it within the movable range. In this way, overall, although the columns are inserted into the ground, their structure is controlled within the movable range. , the advantage of this is that the columns will not break during an earthquake.
In addition, for the rigorous ancients, every brick and tile they used was recorded in detail, and the ancients also used materials, wood, earth and other materials to the extreme.
In addition, thanks to the mortise and tenon structure and brackets developed by the ancients, ancient buildings have taken on a new look, not only looking beautiful but also strong.
In 1973, our country's archaeological team discovered this wonderful mortise and tenon structure during an excavation. According to test results, this mortise and tenon structure has existed for more than 7,000 years, which shows how powerful the wisdom of the ancients was.
Nowadays, although we are in a technological era, we cannot complete 100% structural restoration of ancient buildings.
Like this ancient tower with a history of thousands of years, it has become unobjectionable now. Although it has experienced many earthquakes and bombardments, it was still intact at the time.
Recently, this ancient pagoda has begun to tilt. The reason may be that modern people do not have the same dedication as the ancients.
