Landslide in the Permafrost near a Ministère des Transports du Québec Infrastructure in Salluit and Stabilization Work
Bibliographic record
Abstract
In 2005, a landslide was observed in an erosion gully in marine clay deposits near the Salluit airport access road, directly at the embankment toe. Alteration of the drainage following development in the area seems to have accelerated erosion at the base of the gully. Progressive slide first affected the steeper lower part of the natural slope, and then the active layer in the gentler upper part broke off and slid to the bottom of the gully. By 2008, it affected more than half of the natural slope. In June 2010, stabilization works with rockfill were recommended in the near future. The zone to be stabilizes was extended 40 m downstream of the landslide, where fissures were also observed in the natural slope. Before the works even started, a landslide occurred in the downstream fissured slope on August 22nd, 2010. Contrary to the slow, progressive first landslide, this one took place in one or two large movements of material that carried most of the active layer from the embankment toe to the bottom of the gully. The stabilization that was recommended in June 2010 to stop the progression became an urgent matter to ensure the sustainability of the road, and optimized rockfill was put into place following the latest landslide. A detailed schedule was established for the work to be carried out safely, especially in the remoulded active layer. The events of 2010 prompted the MTQ to increase its monitoring of the existing Salluit airport access road built mainly on marine clay deposits.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
