Norilsk Nickel prepares to create permafrost polygons
They will have to study the territories and choose the best places for the construction of such polygons, ttelegraf.ru reports.
In the summer the construction of observation wells, soil sampling and the first laboratory tests will begin in the selected territories. The concept of organization of permafrost landfills on the territory of the Norilsk Industrial District was developed jointly with scientists of the Research Center for Construction Technologies and Monitoring of the Condition of Buildings and Structures of the Arctic of the N.M. Fedorovsky Polar State University.
Positive feedback on this joint work was received from scientists from several specialized Russian universities and research centers, including Lomonosov Moscow State University and the P.I. Melnikov Permafrost Institute of the Siberian Branch of Sciences of the Russian Academy of Sciences.
"The creation of permafrost polygons will help not only in terms of studying permafrost and observing temperature regimes, but also in the future will answer the question of how else it is possible to build in the Far North," explains Giorgi Kunchulia, head of the adaptation department of scientific research in the field of climate change at the Polar Branch of Norilsk Nickel. "The company has already received a request about the possibility of using the landfill as an experimental testing site for screw pile foundations."
A similar permafrost landfill has already been created in Igarka.
