Abstract
Three-dimensional (3D) probabilistic slope stability analysis using limit equilibrium methods is a time-consuming procedure. Using traditional sampling methods such as Monte Carlo or Latin hypercube may take days of computation, especially when there are multiple random variables and complicated geometries involved. Stochastic response surface (SRS) method is a very fast and effective approach for probabilistic analysis of 3D complicated geometries, which reduces the number of simulations and simulation time dramatically. The SRS method uses a small number of samples that cover the parameter space to train the model. Any number of samples can then be plugged into this model and will result in the estimated factor of safety values for each sample. In this study, an SRS algorithm using third-order Hermite polynomial expansion that works effectively for complex 3D probabilistic analysis is presented to show the performance of this method in the probabilistic analysis. A complex open pit model with several random variables has been investigated using the SRS method, and the results are compared with Latin hypercube simulation results. The results using both methods are in good agreement. However, the SRS method computation time was about 7% of that of the Latin hypercube computation.

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
