Canadian Liquefaction Experiment (CANLEX): Blast-Induced Ground Motion and Pore Pressure Experiments
Bibliographic record
Abstract
Abstract As part of the Canadian Liquefaction Experiment (CANLEX), single and multiple explosive charges were detonated in a level deposit of loose, saturated, sand-size mine tailings. Empirical equations were developed from pore pressure and ground motion recorded at several locations. A condition of zero effective stress was induced at a depth of 6 m when peak particle velocity exceeded 0.65 m/s for single detonations and 0.13 m/s for twelve detonations having millisecond delays. Little or no excess pore pressure was induced from single or multiple detonations when peak particle velocity or peak compressive strain was less than 0.01 m/s or 0.001 %, respectively. The blasting experiments were conducted and analyzed to determine blast-induced ground motion and pore pressure response in a level deposit and to determine the possibility of using explosives to trigger flow-liquefaction in tailings located below an embankment, while keeping peak particle velocities within limits set by Syncrude Canada, Ltd.

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.
