Abstract
Tension crack accelerates the infiltration of rainwater into the soils in the vicinity of a tension crack, which in turn diminishes the contribution of matric suction towards the shear strength of the soil, ultimately leading to the failure of an unsupported trench. Hence, the hydraulic conductivity function of a tension crack is a crucial factor that should be considered in analysing the stand-up time of an unsupported trench under a rainfall event. In this study, a series of numerical analyses were carried out using geotechnical modelling software, SLOPE/W and SEEP/W (GeoStudio 2020) to investigate the influence of hydraulic conductivity of tension crack on the stand-up time of unsupported vertical trenches, considering multiple groundwater table levels and rainfall intensities. Seepage through a tension crack was simulated by using four different approaches available in the literature. To better understand the seepage through a tension crack, an instrumented large-scale field test was utilised as a case study. The results showed that a tension crack can be simply simulated as a void space by applying influx boundary condition along the bottom of tension crack.

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 it
