3D Block Stability Risk Assessment for Rock Slopes
Model 3D Geological Structures
For 3D slope geometries of benches, highway cuts, and entire open pits, model structurally controlled failure in rock slopes exhibiting jointing (faults, joints, bedding, folds, foliations). Define joints as any combination of measured joints, synthetically sampled joint sets, or discrete surfaces, defined by orientation and location.
Block Stability Analysis
Determine all valid blocks which could be formed by the intersection of joints. Once blocks are computed, determine each block’s stability using the limit equilibrium method to obtain a factor of safety, taking into considering weight, shear strength, water pressure, loading and supports.
Predict the locations and magnitudes of failures over the extent of the slope by creating heat maps to show locations with the lowest factors of safety, largest failure volumes and depths, and greatest support requirements.
Probabilistic Analysis
Perform probabilistic analysis to model the variability in rock unit weight, joint shear strength, and water pressure parameters and obtain locationspecific probabilities of failure. Generate statistical plots like histograms, cumulative and scatter plots for any selection of blocks, and fit distributions and regression lines through the data.

RocSlope across Applications
Assess and locate large and smallscale failures across the benches of an open pit as part of optimal pit design, safety planning and risk mitigation during the design and operational stages.
Geological hazard assessment of the stability of rock slopes adjacent to or overlying civil infrastructure such as roads, highways, railways, and bridges. Apply slope stabilization measures by modeling the effects of rock reinforcements and drainage.
Explore the latest features in RocSlope
Display a listing of all block results including information about geometric removability, factor of safety, weight, volume, driving and resisting forces, sliding direction, failure mode, required support pressure, and failure depth. You can filter and export this information as a CSV file.
Focus on critical regions of your model by adding volumetric limits as any combination of inclusion and/or exclusion zones for the computation of blocks along portions of the slope.
Identify key blocks which control potential largescale failures of the slope and simulate the successive unraveling of the slope as key blocks fail and are detached.
