Session: Cold Regions Geotechnics

ABSTRACT: Changes in temperature can lead to thawing and degradation of permafrost and consequent issues related to the integrity of linear infrastructure such as highways. This paper presents thermal numerical modelling for an instrumented highway embankment on degrading permafrost. The instrumented site is located 18 km north of Thompson, Manitoba on Provincial Road (PR) 391. Thermistors were installed beneath the toe, mid-slope, shoulder and centerline of the embankment. Monitored ground temperatures were used to calibrate the thermal numerical model.

RÉSUMÉ: Les changements en température mènent à la dégel et à la dégradation du pergélisol et en conséquence il y a des issues relier à l™intégrité linéaire de l™infrastructure tel que des routes. Ce papier présent la modélisation thermique numérique de la dégradation du pergélisol pour une levée instrumentée d™autoroute. Le tel site est situé 18km au nord de Thompson, Manitoba sur la route provinciale 391. Des thermistances étaient installées en-dessous du front, de la mi-pente, de l™accotement et de la ligne médiane de la levée. Des températures du sol régulées ont été utilisées pour calibrer le modèle thermique numérique.
