Fundamentals of the development of geotechnical and environmental monitoring of the Coastal zone and the water area of the Northern Sea route

Résumé fourni par la source

Introduction. The article is devoted to monitoring the condition of permafrost soils in the Arctic zone of the Russian Federation. Intensive development of the Arctic combined with climate change leads to permafrost degradation and reduced stability of structures in the region. High rates of temperature drop in the air and soil of the coastal zone and the water area of the Northern Sea Route are indicated. Aim. Analysis of the state of the permafrost monitoring system and proposals for the creation of a system of geotechnical and environmental monitoring of the coastal zone and the water area of the Northern Sea Route. Materials and methods. The article presents the main aspects of geotechnical monitoring: assessment, control and forecast of the thermal condition of permafrost soils and assessment of the bearing capacity of foundations of engineering structures. Results. There is an unsystematic approach to monitoring frozen soils, despite the existing regulatory framework and technical support. The necessity of creating a comprehensive system of state monitoring is indicated. Conclusions. The necessity of background monitoring of the ecological and climatic consequences of the degradation of terrestrial and underwater permafrost is substantiated. Recommendations are given on monitoring in key areas of ground permafrost, including the coastal Arctic zone and underwater permafrost in the coastal zone and in the waters of the Northern Sea route.
