Abstract

fetched live from OpenAlex

Numerous ground improvement technologies have been developed over the last few decades to address problematic soils, marginal sites, and geohazards. Soil erosion is a leading geohazard causing infrastructure damage during storm and flooding events. Researchers have studied various bio-treatment methods to decrease erosion susceptibility of coarse-grained soils. Bacterial Enzyme Induced Calcite Precipitation (BEICP) was explored in this study to increase undrained shear strength and decrease soil erosion from moving water. This research investigates the surface erosion control for the mixture of 20-30 standard Ottawa sand and Iowa Western loess silt stabilized by BEICP applied by a spray method. The results obtained in this study indicate that the higher enzyme concentrations increase the surface shear strength and that the formation of the calcite precipitation provides increased resistance to erosion. The depth of the calcite precipitation into the soil specimen was also investigated.\nSoft soils are also considered problematic soil due to their low undrained shear strength and compressibility. Various methods have been used to increase the shear strength such as addition of fibers, shredded rubber tires and geosynthetics. This research investigates adding magnetic particles and using a magnetic field to rotate the particle orientation to increase the shear strength of soft soils. A soft soil surrogate (laponite) which is also a transparent material, was used to visualize the rotation of the magnetic particles. The addition of the magnetic particles was shown to significantly increase the undrained shear strength. Preliminary work using a controllable electro-magnet to create a magnetic field to rotate the orientation of the magnetic particles at small scale is also presented.

Teacher imitation

Not 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.
