Qin Shi Huang, the first emperor of the ancient world, has been famous for the great cause of reunification, but he has been infamous because of his harsh government and fierce tigers, he is the first emperor of China, and the imperial system he left behind has also existed in China for nearly two thousand years, which can be regarded as the first emperor of the ages. However, we know very little about the tomb of this emperor of the ages, only that it is at the foot of Lishan Mountain, unearthed his guard troops terracotta warriors, from Sima Qian's historical records of some things about his underground palace, and there is a water galaxy, although the Qin Shi Huang Mausoleum underground palace has not been excavated so far, but from the records of the history books and the survey of experts, we have also developed a very strong interest in it.
"Wear the three springs, go down the copper and make it, and the palace view of the hundred officials and strange artifacts will migrate to Zang Manzhi, so that the craftsman can make a crossbow arrow, and those who penetrate close to it will shoot it." With mercury as a hundred rivers and seas, organic instilling, upper astronomy, lower geography, mermaid paste as a candle, the degree of immortality for a long time "archaeologists also use this as a clue to detect the situation of the underground palace, but also did detect mercury anomalies. According to speculation, the underground palace is huge, with a total area of 41,600 square meters, equivalent to the size of five football fields. The top of the tomb has a carved pattern of astronomical stars, and at the bottom there are mountain murals and mercury rivers, so that Qin Shi Huang still ruled his country.
The cost of this mausoleum is also enormous, from the beginning of Qin Shi Huang's ascension to the throne, until his death was not completed, it took decades of time, 700,000 labor.
But such a large underground palace, it is very difficult to cap, plus to the present two thousand years, has experienced countless natural and man-made disasters, earthquakes, tomb robberies, Qin Shi Huang mausoleum is still almost intact, what is the reason, it can exist in such a harsh environment for two thousand years. How is it capped and what structure makes it so strong?
As a mausoleum, the first consideration is the problem of water seepage, even in the construction of tombs now, the problem of water seepage is also a problem to be considered first, the mausoleum of Qin Shi Huang is dug to the depth of groundwater, and then built with copper that cannot penetrate water, and then consider the location of its coffin, the hidden mechanism, the mercury river, and the luxurious structure of the interior, gold and silver jewelry.
The second is the problem of its capping, like such a large scale, generally directly sealed a flat roof is easy to collapse, so the principle of triangular stability used, should be the arched capping structure, so such a structure is not easy to collapse, secondly, the area of this dungeon is not an empty large room type, it is divided into many parts, including the main burial chamber, side chamber and tomb passage, each part is a wall made of thick stone slabs, so that these walls also bear a part of the weight. Coupled with the vault capping, this reinforces its structure, and even if it is washed away, the soil will scatter and wash away with the capping of the arch. Its solid structure also enabled the Mausoleum of Qin Shi Huang to survive several major natural disasters and remain to this day.
