Sep-Numerical Coupling Simulation of Groundwater Flow and Deformation in Excavation of Foundation Pit
Bibliographic record
Abstract
The interaction between groundwater flow and soil skeleton plays an important role in the excavation of the foundation pit. This interaction phenomenon affects the water head, the soil settlement, the deformation, and responses of the excavation wall. However, the current simulation of excavation problems usually employs uncoupled analysis between flow and deformation. This paper presents a numerical coupling simulation of groundwater flow and deformation in the excavation process of the foundation pit. The numerical model is verified by published work. Subsequently, the groundwater flow and total discharge entering the excavation were investigated for four types of soils, namely clay, silt loam, sandy loam, and loamy sand. In addition, the dissipation of excess pore pressure was analyzed with different ratios of excavation rate (ER) to soil permeability k. Problems with ER/k >104 can be analyzed using an undrained assumption, while a drained analysis is appropriate for those with ER/k < 100. A fully coupled approach is suggested for the remaining values of ER/k. Finally, the differences in the responses of the retaining wall due to those assumptions were evaluated.

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.
