Stability analysis of accumulation body based on monitoring results of deep displacement
Bibliographic record
Abstract
The stability of accumulation body commonly adopts a qualitative and quantitative analysis method, which considers the geological boundary conditions, calculation model and mechanical parameters of rock mass and so on This causes the stability results be limited, so it is unlikely to make a real-time quantitative evaluation on the accumulation body.This paper proposes a method which avoids these problems, and timely evaluates the accumulation stability based on the monitoring results in the process of the deformation development.It involves two parameters, i.e. the integrity index S(i) and the destructive index S(d), used to evaluate quantitatively the dynamic change of accumulation body when the progressive destroy occurs from the bottom up.Take talus in front of the dam of Zippingpu hydraulic project as an example, this method not only measures the S(i) and S(d) during movements of its reservoir water level, but also evaluates the impact of Wenchuan earthquake on the accumulation body.it is proved by an example that this method is convenient, practical and feasible.. RÉSUMÉ.Afin d'analyser la stabilité du corps d'accumulation, généralement une méthode d'analyse qualitative et quantitative est adopté e, qui prend en compte les conditions des limites gé ologiques, le modè le de calcul et les paramè tres mé caniques de la masse rocheuse, etc. Cela entraî ne une limitation des ré sultats de stabilité , de sorte qu'il est peu probable qu'une é valuation quantitative en temps ré el du corps d'accumulation soit ré alisé e. Cet article propose une mé thode qui évite ces problèmes et évalue en temps voulu la stabilité de l'accumulation en fonction des ré sultats de la surveillance dans le processus du dé veloppement de la dé formation.Il implique deux paramè tres, à savoir l'indice d'inté grité S (i) et l'indice de destruction S (d), utilisé s pour é valuer quantitativement le changement dynamique du corps d'accumulation lorsque la destruction progressive a lieu de bas en haut.En prenant comme exemple le talus devant le barrage du projet hydraulique de Zippingpu, cette mé thode mesure non seulement les indices S (i) et S (d) lors des mouvements du niveau de son ré servoir, mais é value é galement l'impact du séisme de Wenchuan sur le corps d'accumulation.Un exemple montre que cette mé thode est simple, pratique et ré alisable.

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.
