Study on the Thermal Regime of Permafrost underneath the Tasiujaq Airstrip near Ungava Bay Coast, Northern Quebec
Publication: Cold Regions Engineering 2024: Sustainable and Resilient Engineering Solutions for Changing Cold Regions
ABSTRACT
Observed and projected climate warming affects the thermal stability of airstrip foundation in Nunavik, Canada. Intensive maintenance is needed to keep a reasonable service level. The paper focus on a case study of permafrost beneath the airstrip embankment at Tasiujaq, Nunavik. Field measurements of 6 years thermal data have been used to calibrate a 2D finite element model developed to reproduce the thermal condition of airstrip foundation and simulate soil temperatures. The model developed was well calibrated to the measured temperature data, supporting the reasonable accuracy of developed model. Specific interest was paid to the side slope, where rapid permafrost degradation was expected. One adaptation solution was also proposed, based on documented thermal stabilization approach.
