RocPlane
Planar Wedge Analysis for Slopes
An essential part of your rock slope analysis toolkit, RocPlane is an easy-to-use tool for the analysis and design of planar wedge stability. RocPlane is a very useful tool for geotechnical engineers analyzing bench stability in open pits and rock slopes.
RocPlane is an interactive software tool for performing planar rock slope stability analysis and design. RocPlane makes it easy to quickly create planar models, visualize them in both 2D and 3D, and evaluate analysis results. RocPlane contains many helpful features that allow users to rapidly build, modify and run models.
RocPlane also includes functionalities for easily analyzing results, generating figures and charts, and producing convenient summaries of models and results. The report generation features of RocPlane are especially useful to engineers when writing reports with high quality and professional-looking drawings and diagrams. They help slope designers readily communicate findings to people with varying levels of slope engineering knowledge.
About RocPlane
ROCPLANE is a simple to use, interactive software tool for assessing the stability of planar sliding blocks / wedges in rock slopes. It also allows users to estimate the support capacity required to achieve a specified factor of safety.
A planar wedge is a wedge for which sliding occurs on a plane approximately parallel to the face of a slope. ROCPLANE analyzes a slice of unit thickness taken perpendicular to the strike of the slope face. In the program, users have the option of performing either DETERMINISTIC or PROBABILISTIC analyses.
In a DETERMINISTIC analysis, ROCPLANE calculates the Factor of Safety for a wedge of known orientation and other input parameters. For PROBABILISTIC analysis the program allows users to specify statistical distributions for various input parameters, and the number of simulations required. ROCPLANE then computes the Probability of Failure of the wedge by running the analysis the specified number of times, each time generating different values for the stochastic input parameters.
Other important features in ROCPLANE analysis include:
• Water Pressure
• External and seismic forces
• Active or passive bolt support
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.
Probabilistic Analysis
Determine the probability of failure of your model by assigning statistical distributions to variables including the slope geometry, joint orientation and strength, water and seismic forces, and supports. View the statistical data in histogram, cumulative and scatter plots.
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 :
1. Mining
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.
2. Rock Slopes
Assess the planar stability of slopes created by the excavation of rock cuts.
Explore the latest features in RocPlane :
1. Batch Compute
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.
2. Automate from Excel
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.
3. Ponded Models
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.
