Historical experience of geological research and foundation construction on the example of the city of Norilsk.

This article analyzes the experience of geological exploration and construction on the example of the city of Norilsk, and also discusses their problems. In 1935, it was decided to build the Norilsk Metallurgical Plant and the village of Norilsk was founded. During the geological survey and construction, many problems arose, these include: - the spread of permafrost soils, and subsequently the thawing of soils acting as the base of buildings and structures; - a small number and scattered location of rocky soils suitable for use as a base; - limited technology capabilities; - long time and huge costs when using as a base, rocky soils. Those problems mostly arose due to the lack of experience in building foundations on permafrost, Norilsk is the first experience in this regard. To solve the problem of permafrost, the Norilsk Integrated Department of the Krasnoyarsk Institute "Promstroyniiproekt" was formed in 1959. The solution to the problem was found at that time by Mikhail Vasilyevich Kim, who was appointed to the post of head. The method of pile foundation in permafrost consisted in freezing the pile into the frozen ground. Thus, this method allowed not only to solve the problem with the construction of foundations on permafrost, but also to use it for construction purposes.
