Study of the Influence of Sheet Pile Location under Dams on Groundwater Flow and Pore Pressure with Network Method
Bibliographic record
Abstract
The construction of a gravity dam leads to some verifications that may affect its safety, such as groundwater flow or pore pressure distribution under the structure. These phenomena, which are related to piping and the position of the uplift force, can be controlled by placing a sheet pile under the dam. The variables are commonly studied as if the soil was isotropic, simplifying universal results (either graphics or formulations). However, this assumption does not reflect real scenarios in most of the cases, for example anisotropic hydraulic conductivities. In this work, the effects of the sheet pile position in four different cases is studied: dam without a sheet pile and dam with a sheet pile located at the heel, centre and toe of the structure. In all of them two different media are modelled, with isotropic and anisotropic hydraulic conductivities, so its influence can be appraised from the point of view of safety. The scenarios are simulated with a tool based on the network method that, employing the electrical analogy, obtains the problem variables, 'hydraulic potential' (h) and 'water flow' (Q), solving electric quantities, 'voltage' (V) and 'electric current' (I), respectively.

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.
