COMPARATIVE STUDY FOR ESTIMATION OF DYNAMIC STRESS AND STRAIN LEVELS INDUCED BY BLASTING VIBRATIONS
Bibliographic record
Abstract
This study investigates the truthfulness of the claims of damage of the buildings in the City of the 15th of May due to blasting vibrations. A comparative study has been carried out for three case studies: Golden Sunlight surface mine in Montana, Canada; Bani Khalid quarry, Samalout, Minia, and the limestone quarry of the National Cement Company in relation to the city of the 15th of May, Helwan, Egypt. As a result of the study, the magnitudes of the dynamic Young’s modulus, strains, and stresses have been found compatible for Golden Sunlight mine and Bani Khalild case studies. On the other hand, the case of the city of the 15th of May has showed very high magnitudes for both dynamic Young’s modulus and stresses. Hence, re-calculation and re-evaluation have been carried out following the procedures of Golden Sunlight mine and Bani Khalid cases. The obtained new magnitudes of Young’s modulus and stresses are found compatible with Golden Sunlight and Bani Khalid. Accordingly, the conclusions of the previous study on the City of the 15th of May that damages of the buildings in the City are due to blasting vibrations are not acceptable. Re-investigation of the damage in the buildings of the city has to be carried out to find other causes of the damage. These causes may be geological, environmental or even design causes.

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.
