Monitoring blasting-induced vibrations in a Québec clay deposit
Bibliographic record
Abstract
Abstract Blasting operations carried out as part of road projects can generate vibrations that affect the stability of surrounding slopes. However, the effects of these vibrations on clay soils remain poorly documented. To date, few cases of landslides or major deformations have been recorded in these types of soils following blasting. Currently, blasting is controlled by peak particle velocity (PPV) thresholds. In Queébec, existing regulations are becoming increasingly restrictive, leading to a significant increase in blasting costs. This article is a continuation of the recommendations from previous studies, which highlighted a lack of field data on vibrations caused by blasting in sensitive clay deposits, as well as the absence of a clear methodology for carrying out measurements (number of devices, distances between recording sites, etc.). One of the objectives of this article is to show vibration recording data produced by blasting activities in clays in order to gain a better understanding of these problems. As part of this project, two blasting operations were carried out near a clay deposit. Various installation devices and techniques were used to measure vibrations and are presented in this article. These field tests highlighted limitations in the surface recordings, which affect our understanding of blasting wave propagation mechanisms in clay soils. These understanding of blasting wave propagation mechanisms in clay soils. These limitations will be discussed in detail and provide the basis for a subsequent phase of research.

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.
