Neural network-assisted generic predictive models of safety factor and yield acceleration for seismic slope stability and displacement assessments
Bibliographic record
Abstract
As two well-recognized approaches for seismic slope stability assessment, the pseudo-static analysis calculates the factor of safety ( FS) and the Newmark-type analysis estimates the permanent downslope-displacement for given yield acceleration ( ky ). However, FS and ky are usually obtained from nontrivial slope stability calculations, which can become computationally demanding in probabilistic analyses or regional landslide mapping. This study presents neural network-assisted predictive models for (1) seismic or static FS and the category of failure mode; and (2) ky and the thickness of failure mass. Extensive stability analyses of more than 741 000 and 123 000 slope configurations are conducted to compile datasets of FS and ky , respectively. Performance evaluation results indicate that the models produce physically reasonable prediction trends and have good generalization capability with correlation coefficient higher than 0.94 in blind tests. Compared to the infinite slope model and existing predictive tools, the new models achieve improved applicability and functionality, accounting for pore-water pressure, depth to hard stratum, and various failure modes. Both the spreadsheet and MATLAB files established in this study are provided to facilitate generic applications. Therefore, this work not only demonstrates the capability of neural network in slope stability predictions, but also provides useful tools for practitioners, contributing to both the pseudo-static and Newmark-type approaches.

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.
