Tyumen scientists on guard of environmental challenges of our modernity

The climate on the planet is constantly changing. However, what is happening today, according to scientists, is unprecedented, and many climate changes are related to the human factor. One of the main environmental challenges is global warming, which leads to the fact that permafrost is gradually melting. The technological project of the world-class West Siberian Interregional Scientific and Educational Center allows to predict the degradation of permafrost soils.

It may seem that the glaciers are somewhere far away, and their melting will take a long time. However, in fact, this problem is much more urgent and serious. The increase in air temperature leads to the degradation of permafrost soils, which occupy from 60 to 65% of the territory of Russia. The melting of permafrost in the northern regions threatens the destruction of buildings and infrastructure.
This is due, among other things, to the fact that the construction technologies of most structures were based on the fact that permafrost will remain so. Meanwhile, in many northern regions, the average annual temperature has significantly increased. Thawed soil literally goes out from under your feet, which leads to deformation of erected buildings, damage to roads, gas pipelines and other construction sites of northern cities and towns.
The project of the world-class West Siberian Interregional Scientific and Educational Center "Forecast of permafrost degradation and technology of automated control of the bearing capacity of frozen soils under capital construction objects" is intended to contribute to solving this problem.
Given that there is permafrost in most of the territory of the Russian Federation, this task is not only regional, but also all-Russian. The introduction of the technology of automated control of the bearing capacity of frozen soils under capital construction facilities will significantly reduce the losses of the capital fund of Russia due to the degradation of permafrost.
The experimental implementation of solutions developed within the framework of the technological project of the West Siberian REC already makes it possible to increase the service life of capital residential buildings and social facilities, monitor and predict emergency situations, develop and apply engineering solutions in advance before the appearance of deformations of buildings.
For residents of regions of Russia where the problem of permafrost is particularly relevant, this means a qualitatively different level of guarantees of financial investments when purchasing housing in capital execution, insurance against unfair work of management companies. For the regional authorities, this is a mechanism for managing the risks of economic damage, reducing the losses of the capital fund.
11 buildings in Salekhard and Novy Urengoy are already equipped with autonomous permafrost monitoring systems, and several more facilities in the Yamal district (Yar–Sale village, Novy Port village) are planned by the end of 2022. The software and hardware complex "Automatic permafrost monitoring System CAM - Permafrost – T" is currently being registered in the register of measuring instruments of the Russian Federation. The full completion of work on the creation of automated geotechnical temperature monitoring technology and the bearing capacity of the foundations of the foundations of capital buildings is planned for the end of 2024, while the permafrost monitoring system is planned to be created in Russia after 2024.

Work in this direction is planned to be carried out in two stages: from 2022 to 2024 to develop monitoring methods and technologies, and after 2024

start creating them directly. The planned system will include several levels. At the federal level: a single center, with the help of which not only the collection of information will be carried out, but also its processing, analysis and forecast. At the regional and municipal levels: a network of stations that will monitor changes related to the melting of permafrost. And another level is the subsoil users: companies developing deposits, which will also have to observe and submit data to a single center.

The next stage in the development and launch of the permafrost monitoring system is the creation of hospitals for the study of geocryological processes occurring in the permafrost zone. Currently, such work is carried out only by scientific institutions (Lomonosov Moscow State University, Institute of Geoecology of the Russian Academy of Sciences, Institute of Permafrost Science SB RAS, Institute of the Earth's Cryosphere SB RAS, etc.). The study of cryogenic processes is mainly descriptive in nature, their quantitative forecast is based on developments thirty years ago, and methods for preventing dangerous processes are practically not improved. The level of research on changes associated with permafrost melting and their implementation in construction practice do not meet the modern requirements of high technologies and the pace of development of natural resources in the regions of the cryolithozone.

That is why the permafrost monitoring system is so necessary.

All monitoring data are only empirical data reflecting the development of a particular process. However, systematically collected and competently processed information can be used to track the current situation and develop new methods and techniques for predicting the impact of climate change on infrastructure and natural processes. In this regard, it is necessary to develop new quantitative forecasting methods, as well as computer programs.

The volume of Yamal's budget investments in the creation of technology has already amounted to 75 million rubles. Most of the financial resources are directed to the creation and experimental testing of a system of software and hardware complexes, covering a full cycle of work from monitoring the current state of soils to calculating the forecast bearing capacity of each pile element of the foundation of the building, namely: two modifications of software and hardware complexes "System of autonomous monitoring of permafrost SAM – 15- 1 and SAM – 15-IGSM", software for calculating non–stationary thermal fields under buildings with pile foundations in the permafrost distribution zone "TIPFIS", software for calculating the bearing capacity of pile foundations under buildings in the permafrost distribution zone "FrostPileFoundations - 3D". The plans of the government of the Yamalo–Nenets Autonomous District include an annual planned expansion of the network of geotechnical monitoring of residential buildings in municipalities.
