Abstract
Biaxial compressive test apparatus,test techniques and test results of rock materials are reviewed in the paper,and pointed out shortcomings such as most current failure criteria ignore the affection of intermediate principal stress,samples too small to assess the scale effects and the friction between the loading platen and sample which affects the failure mode of sample.In order to eliminate the limitations of the previous apparatus,a new Isotropic Biaxially Loading System(IBLS) which has higher loading capacity than previous apparatus has been designed and is being established by Henan Polytechnic University of China and McGill University of Canada.Steel brush platens will be employed in the IBLS to eliminate the influence of friction between the loaded surfaces of the rock specimen and loading platens,and IBLS can be used to uinaxially and biaxially investigate bigger samples than previous investigations.The investigation results by IBLS might amend the shortages of realization for the strength behavior and failure mechanism of rock material under biaxial compression.

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
