Numerical Modelling of In Situ Stresses to Investigate the Initiation of Spreads in Sensitive Clay
Bibliographic record
Abstract
Abstract Spreads are a type of landslide in sensitive clay, characterized by horsts and grabens that develop over long, quasi-horizontal shear band due to strain-softening and progressive failure. It is not yet understood what causes the initiation of the horizontal shear band, nor why its direction of propagation is approximately horizontal. The paper suggests that initiation of a horizontal shear band is more likely in deposits that have a high capacity for horizontal unloading in the overlying soil mass without mobilizing active failure relative to the direct simple shear undrained shear strength along the potential shear band. Using the 1994 spread at Sainte-Monique-de-Nicolet, two parametric studies are described studying the influence of various soil strength parameters on the ratio of available horizontal unloading to direct simple shear strength as well as the influence of this ratio on mobilized stresses following a horizontal unloading. The results of a recent phase of geotechnical investigation, used to identify soil input parameters, are described.

How this classification was reachedexpand
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.
