Geotechnical input to the design, construction, and operations of pipelines in permafrost may differ significantly from that for pipelines in temperate terrain. The general remoteness and terrain fragility of permafrost regions are key issues that challenge the geotechnical input. Specific geotechnical issues that necessitate input include pipeline routing, slope stability, thaw settlement and frost heave, ditching, buoyancy control, upheaval buckling. and others. It is necessary to develop and implement new technological solutions, taking into account long-term forecasts of the temperature conditions of the soil bases, which should be able to prevent or compensate for the negative impact of heat for all pipelines laid in permafrost conditions.
