Sensitivity analysis of laterally loaded piles embedded in stiff clay above water table.
Bibliographic record
Abstract
This study presents the theoretical formulation and numerical investigation of sensitivity analysis of laterally loaded piles embedded in stiff clay located above the water table. Single piles with various lengths and boundary conditions subjected to static and cyclic loadings applied to the pile-head as lateral forces and bending moments are analyzed. The cyclicity is introduced explicitly to p-y curve. The p-y soil response is of quasi static type. The pile groups of 3 x 3 piles with various spacing (2D, 3D, 4D and 5D) are also analyzed in the study. For single piles, the pile structure is considered as one-dimensional beam and the supporting stiff clay is defined by means of p-y relationship. For groups of piles, the pile members are considered as one-dimensional beams and the pile cap is considered as plate. The behaviour of a pile-soil system in the pile group is simulated also by means of p-y relationship, which is modified by the fm factor that is dependent on the spacing of the piles and the locations of the piles in the groups. The pile material parameter and soil physical parameters are taken as the design variables. The adjoint method for nonlinear system is used to analyze the sensitivity of the piles and pile groups. The changes of maximum generalized deflection located at the pile head of the pile due to the changes of the design variables are explored by means of sensitivity integrands associated with each of the design variables. The numerical results in terms of spatial distributions of sensitivity integrands are presented and discussed in detail. The sensitivity integrands are integrated and the assessment of the result is carried out. The Matlab programmings are used to conduct the numerical investigations of single pile and pile groups.* *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation).Dept. of Civil and Environmental Engineering.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
