Abstract
Microparameters of the clay component of an earth fill dam need to be identified in order to develop a reliable discrete element landslide model. To characterize clay microparameters, a calibration process of matching the simulated and actual undrained consolidated triaxial test results were performed. Linear parallel-bond model was used to describe the interactions of clay particles. The microparameters calibrated to match the real clay behavior were particle stiffness, friction, bond stiffness, and bond strength. Sensitivity analysis revealed that bond stiffness and bond strength dictate the peak stress behavior of the numerical model, while particle stiffness and friction influence its critical-state stress behavior. The designed calibration methodology based from the sensitivity analysis results was able to identify a suitable set of microparameters that can simulate the real behavior of clay. Integrating the calibrated microparameters to the numerical model yielded good agreement between the measured and simulated stress-strain relationships of clay at different consolidation pressures.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
