A Novel Procedure for Physical Modeling of Unsaturated Soil-Pile System Using Geotechnical Centrifuge
Bibliographic record
Abstract
The mechanical and flow behaviors of unsaturated soil are affected by the degree of soil saturation, the load carrying capacity of pile foundations supported on unsaturated soils are affected as well. This paper describes a geotechnical centrifuge testing procedure developed for evaluating the effect of degree of saturation on the static and dynamic response of pile foundations. Specifically, the specimen preparation, testing procedure, and sample test results are presented. A uniform degree of saturation profile with depth was obtained by spraying water from the top of the model. The water was stored in a pre-pressurized inflow tank attached to the centrifuge platform. The flow rate was controlled using servo valves, and the model dimensions were scaled using centrifuge scaling laws. The experiments were conducted in Ottawa sand at 50 g centrifugal accelerations. Results from 24% and 28% degree of saturations are presented with important suggestions based upon our experience.

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.
