Description
Summary:Arctic settlements built on permafrostface rather unique set of geotechnical challenges. On urbanized areas, technogenic transformation of natural landscapes due toconstruction of various types of infrastructure leads to changes in heat exchange in permafrost-atmosphere system. The spatial distribution and intensity of dangerous cryogenic processes in urbanized areas is substantially different from natural background settings found prior to construction. Climate change, especially pronounced in the Arctic, exacerbated these changes. Combination of technogenic pressure and climate change resulted in potentially hazardous situation in respect to operational safety of the buildings and structures built on permafrost. This paper is focused on geotechnical safety issues faced by the Arctic urban centers built on permafrost. Common types of technogenic impacts characteristic for urban settlements wereevaluated based on field observations and modeling techniques. The basic principles of development of deformations are discussed in respect to changing permafrost conditions and operational mode of the structures built on permafrost.
