Abstract
The growth of ore treatment rates during the last decades has required an increase in the tailings impoundment capacity. Consequently, the height and volume of the designed sand dams have reached unprecedented dimensions. This has been caused by environmental constraints according to current regulations. In this context, the sand dam design with the centreline method is an alternative to reduce the sand volume without affecting the global dam stability. This method of construction has been applied successfully in seismic countries with high tailings dams such as Canada and more recently in Peru. This article presents 2D numerical modelling of high tailings dams under a strong seismic event. For this analysis it has been considered a standard section of dam built by downstream in one case. A second case considers the same section modifying its growth method to centreline from a certain height. The seismic response for both methods and the effect of variation in the upstream slope, in terms of seismic deformations, crest accelerations, amplification respect to free field and among others, are compared.

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.
