Détermination de l’hydrogramme de rupture par déversement en crête pour barrages en terre et en enrochement disposant d’un rideau en béton
Bibliographic record
Abstract
Il existe une relation directe entre les caracteristiques de l’inondation qui decoule de la rupture d’un barrage lors de sa submersion et la breche qui se forme au sein de l’ouvrage. Afin d’apprehender le risque de rupture par submersion des barrages en remblai, une approche normative a ete adoptee au Quebec. Cette norme se base sur des ruptures existantes et prevoit, pour les barrages en remblai, la formation, en trente minutes, d’une breche trapezoidale de hauteur H et de largeur au fond 4H. L’utilisation de cette norme ne permet toutefois pas de prendre en compte les caracteristiques propres de chaque barrage et notamment l’utilisation d’un noyau en beton comme element d’etancheite. Seulement, les incertitudes sur la prevision de la breche font que dans l’etat actuel des connaissances, l’utilisation de cette norme reste la solution la plus fiable. Le present article decrit un modele de rupture par submersion du barrage Nemiscau–1, le premier barrage a noyau en beton bitumineux du Quebec. L’etude porte ...

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.
