A Using 3D CAD and digital simulation tools, the great pyramid has in a way been virtually reconstructed, with the aim of validating a daring hypothesis: it would have been built from within. After eight years of research, with the help of a dozen specialists from Dassault systems and thanks to heavy IT resources, an architect, Jean-Pierre Houdin, has just presented a very convincing thesis which explains the construction of the great pyramid, called Cheops. Erected more than 40 years ago, when the rest of the world was still in prehistoric times and was plunged into barbarism, this pyramid was renovated by Pharaoh Khufu, who the Greeks will call Khufu, this monument nearly 000 meters high originally has always fascinated. The secrets of its construction have been lost by the Egyptians themselves. More than two thousand years later, the Greek Herodotus is already trying to understand how such a giant could have been raised and evokes mysterious machines, functioning like cranes.
Since then, we have not counted the hypotheses imagined to reconstruct the method of the Egyptian builders, from the most plausible to the most eccentric. This is what François de Closets mentioned one day in 1999 in a television program. In front of his post, the father of Jean-Pierre Houdin, who was a construction professional, said to himself that all this does not hold water and wonders how he himself would have done it. He would have, he thinks, started the construction with the external facing. Thus, the shape of the building is more easily controlled while the interior can be filled with stones of various sizes, roughly adjusted. Second idea: build an internal gallery, just a few meters behind the wall, with a low slope, which will meander to the top, allowing the stones to be transported throughout the construction.
Reconstitute the building site
It was his son who got down to the task of testing this vision with another idea: to use the CAD and digital simulation computer tools used by manufacturers to develop a product. Today, car manufacturers hardly need to perform an actual crash test on a new vehicle: it is a computer that simulates the most varied shocks and precisely calculates the effects of the impact. . Likewise, specialized software can simulate all stages of manufacturing. So why not build a pyramid in this way, checking that all the processes are realistic, then testing their solidity?
