Permafrost engineering problems at the turn of the XXIth century

Permafrost engineering problems are considered in this paper. These have resulted from the intensive anthropogenic changes of the environment that have occurred in recent years. Areas of concern include: management of thermomechanical processes in the built-up and industrialised areas, creation of ecologicallyclean building technologies, estimation of reliability of geotechnical systems and optimisation of the associated costs, creation of effective ways of ground cooling and use of frozen ground for the long-term burial of nuclear wastes. The outcomes of these studies have been analysed in this paper. Further scientific research, which will contribute to the acceleration of technological progress in the development of the northern territories and the associated sustainable management of the permafrost, are also discussed.
