Rocscience RocPlane
Graphical and Statistical Analysis of Orientation Data
Planar Rock Slope Analysis
Quickly and easily define planar wedge models, visualized in 2D and 3D. Perform planar sliding stability analysis using Limit Equilibrium Method. Model the effects of joint shear strength, water pressure, seismic and external forces, and supports in the computation of the factor of safety.
Bench Design Tools and Charts
Conduct Bench Design as an extension of RocPlane’s Probabilistic analysis feature. Input design parameters and statistical joint information to optimize the bench slope angle. Calculate required bench width, considering spill width and backbreak distance. Results can be output using a number of different statistical charts including total probability of failure, volume of failed wedges, minimum bench width, and backbreak cell probabilities.

RocPlane across Applications
Assess the probability and scale of localized bench failures. Design adequate bench widths and slope face cuts using bench design tools to reduce the risk of failed material from reaching operating levels below.
Assess the planar stability of slopes created by the excavation of rock cuts.
Explore the latest features in RocPlane
Save time with the Batch Compute feature which enables you to compute several deterministic and/or probabilistic RocPlane model files (.pln, .pln4) at once and quickly generate results to text or Excel format.
Automate a deterministic or probabilistic analysis in RocPlane by reading in various numerical input data from an Excel template, and quickly generating computed results to text or Excel format.
Apply Ponded Water Pressure to the Slope and/or Upper Face by specifying the depth of ponded water. Plane Water can also be modeled in conjunction with Ponded Water with assumption of either pervious or impervious slope face.
