APF PlaneFailure 3.1

APF PlaneFailure 3.1

APF PlaneFailure is a focused slope stability analysis program that calculates the factor of safety (FoS) against sliding for slopes where failure is assumed to occur along a discrete, planar geological discontinuity (such as a bedding plane, joint, or fault). The software models the forces acting on the potential sliding block, including gravity, water pressure, seismic forces, and external reinforcement (rock bolts, anchors), to determine stability under various conditions. It is a critical tool for assessing the safety of natural slopes, designed cuts, and mine highwalls where planar geology controls stability.

⛰️ Primary Users

APF PlaneFailure is a specialized geotechnical engineering software designed for Geotechnical Engineers, Slope Stability Analysts, Mining Engineers, Civil Consultants, and Infrastructure Designers who need to perform deterministic and probabilistic analysis of slope stability using the planar failure method, commonly applied to rock slopes, embankments, and open-pit mine walls.

✨ Key Features & Capabilities

• Planar Failure Analysis: Core calculation engine for analyzing sliding of a block on a single plane, incorporating variables like dip, dip direction, friction angle, and cohesion.

• Water Pressure Modeling: Accounts for water pressure in tension cracks and along the failure plane, which is a major destabilizing factor.

• Seismic (Pseudo-Static) Analysis: Applies horizontal and vertical seismic coefficients to simulate earthquake loading on the slope.

• Support Design Integration: Models the stabilizing effect of passive (rock bolts, dowels) and active (tendons, anchors) reinforcement systems.

• Probabilistic & Sensitivity Analysis: Performs Monte Carlo simulations to assess the impact of variable input parameters (e.g., friction angle, cohesion) and calculate probability of failure. Identifies the most sensitive parameters.

• Graphical Output & Reporting: Generates clear diagrams of the slope geometry and failure wedge, along with detailed calculation reports for documentation and review.
