Verification of the CSDS Model in Estimating the Postpeak Behavior of Hard Rocks
Bibliographic record
Abstract
Rockburst is a serious instability problem in Canadian deep underground excavations and is related to the postpeak behavior of hard and brittle rocks. Rockburst potential can be estimated by comparing the postpeak stiffness of the failed rock and the prepeak stiffness of the surrounding rock. Estimation of the postpeak behavior of hard and brittle rocks can help engineers evaluate and predict potential severe instabilities. The complete stress-displacement surface (CSDS) model is an analytical model (a constitutive model for rock joints) that estimates rockburst proneness. This paper aims to verify the application of the CSDS solution for estimating the postpeak curve (postpeak stiffness) in intact hard rocks by experimental results. To verify the model properties used in the model, different types of rock mechanics tests have been performed. The results show that the CSDS model can be used to estimate the postpeak behavior of medium to hard rocks.

Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
