Bibliographic record
Abstract
This report is a compilation of underground cases with observed and documented field data, where rock mass failure has occurred and deformation has been monitored. The cases presented within this report were selected on the basis of the following requirements: - Failure has occurred in the excavation as a result of stress- induced failure, structurally-controlled failure, or a combination of both. - Measurement of deformation has been conducted before and during both the excavation and time of the failure occurrence. The information presented in this report is based on documented information such as papers and articles, formal reports, theses, and communication via email with researchers and consultants. Five cases are presented in five chapters within this report: - Mine-by Experiment - Chapter 2. - Heathrow airport tunnel collapse - Chapter 3. - Instrumented drift at the Kiirunavaara mine - Chapter 4. - Arlandabanan tunnel - Shuttle station 2 - Chapter 5. - Äspö Pillar Stability Experiment - Chapter 6. The first two cases are tunnels from Canada and England and the last three cases are from Sweden.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
