I am interested in doing probabilistic analysis using geotechnical software. My own reviews I am looking to do probabilistic analysis in Plexis software, but I could not find how to do this analysis in the software, please guide me.
Please check out this video that will show you the steps to do a probabilistic approach.

If you need probabilistic finite element analysis, use RS2 (Rocscience).
According to https://www.seequent.com/products-solutions/plaxis-le/ , performing limit equilibrium analyses with PLAXIS LE is essential for LEM slope stability analysis. Accomplishing engineering analyses of slope stability, groundwater flow, and consolidation.
"PLAXIS 2D LE and PLAXIS 3D LE are powerful applications for limit equilibrium slope stability analysis and finite element analysis of groundwater seepage.
Perform rapid and comprehensive analyses
Determine the full 3D slip surface at hundreds of locations in extensive models, such as open-pit mines, riverbanks, and road and rail corridors with multi-plane slope stability analysis (MPA).
Automatically calculate the slip direction at each location using orientation analysis features. Design with confidence when considering faults, weak planes, and pore-water pressures.
Get access to the most available search methods on the market including Greco, Cuckoo, Wedges. Use probabilistic analysis such as Monte Carlo, Latin Hypercube, and the Alternative Point Estimation Method (APEM) to build robust digital twins. Further refine models with sensitivity analysis and spatial variability features.
Analyze slopes with various methods
Calculate safety factors and increase accuracy using 3D analysis of site geology to ensure infrastructure safety and reliability. Perform analysis with limit equilibrium method of slices or stress-based methods. Choose from classic method of slices like Bishop, Janbu, Spencer, Morgenstern-Price, GLE, and Sarma methods. Perform hybrid Kulhawy analysis by importing stress fields in 2D and 3D.

Advanced Probabilistic Slope Stability Analysis on Rissa Slope
Amanuel Petros Wolebo
Norwegian University of Science and Technology, 2016
"Abstract
Uncertainties on different soil properties affect the reliability of geotechnical analysis. In geotechnical design the most adopted procedure to account for uncertainty is, to maintain some degree of safety by using characteristic values and factor of safety approaches. This method does not give a complete indication of safety margin. Too high safety standards cause expensive system, whereas too low factor of safety results many casualty and economic damage. How the uncertainties in soil parameters affect the geotechnical reliability analysis should be dealt adequately and the uncertainties should be quantified and carefully evaluated. This thesis focuses on the evaluation of the effect of uncertainty and soil variability on stability analysis within the formwork of probabilistic methods and contributes to the application of advanced probabilistic method in geotechnical slope stability analysis. Conditional random finite element method (CRFEM) creates a computational model able to estimate the probability of failure of a slope while fully accounting for for spatial variability of soil. The applicability of CRFEM shows the potential of the framework of uncertainty quantification and the effects of soil variability and spatial variability at different scales on the studied case. The case study is based on the ground investigation made while planning a road project in Rissa area located in SørTrøndelag, Norway. The area is famous for the quick clay slide that occurred in 1978."
in my article, I compared outputs of plaxis with nntools in seepage field.
