RESUMEN: Los cambios en la temperatura afectan las obras de Ingeniería Civil, particularmente en áreas con temperatura promedio cercana a 0°C donde el permafrost es localmente discontinuo. El calentamiento global y las acitividades humanas pueden llevar a incrementar la temperatura del permafrost y generar descongelamiento. En regiones de permafrost discontinuo, el descongelamiento puede ocasionar el incremento de la capa activa del permafrost, aumentar los asentamientos del suelo y crear deformaciones cortantes irrecuperables. Este artículo examina el comportamiento de un terraplén para una carretera localizado aproximadamente 18 km al noroeste de Thompson, Manitoba. La investigación involucra pruebas de campo, instrumentación, pruebas de laboratorio y modelamiento númerico. El artículo presenta resultados de monitoreo durante los dos primeros años de operación, es decir, durante dos ciclos de congelamiento/descongelamiento. Los resultados proveen una evaluación de las causas de la deformación de terraplenes y los mecanismos que producen la falla funcional (estados limites de servicio) de las carreteras construidas en permafrost degradado.
