Abstract
Environmental considerations are an important aspect of construction activities, such as the impact of construction vibrations at project sites and in nearby properties. There are limited studies to investigate the impact of vibration from ground improvement construction and how underground utilities can be protected from vibration damage. This research is aimed at developing empirical formulations that can be used to predict ground particle velocities near buried structures. This will allow engineers to minimize potential vibratory damage to buried structures. In this study, ground vibrations are produced by the installation of rockfill columns, a ground improvement technique to stabilize riverbanks. Installation of rockfill columns was done near a buried aqueduct. So, there is a concern that this aqueduct can be damaged by ground vibrations. Finite-element analysis was done to provide information on ground vibrations caused by the installation of rockfill columns. The finite-element models were calibrated with particle velocities measured at the construction site. Results showed that the particle velocities obtained in the numerical models correlated well with the measured particle velocities and those reported in the literature (although from different sources of vibrations). Empirical relationships are proposed between ground vibrations and their impacts on nearby buried structures.

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 it
