Overview

RocTunnel3 is a 3D limit equilibrium program developed by Rocscience for evaluating the safety factor of structurally-controlled block failures in underground rock excavations. It determines valid block formations by intersecting joints in 3D space and calculates the factor of safety for each block using the 3D limit equilibrium method.

Features and Capabilities

• Deterministic and Probabilistic Block Stability Analysis: Find valid block formations by intersecting joints and calculate the factor of safety in deterministic analysis. You can sample rock unit weights, joint shear strength, and water pressure across simulations to calculate block failure probability.
• Staged Excavation and Support Design: Analyze block stability and the required support pressure and support depth in every construction stage for meeting a user-specified design target. Design shotcrete, support pressures, and bolts in stages to address the challenges of structurally controlled failures underground.
• 3D Geological Structures: Model realistic 3D underground excavations in complex geological domains and structurally controlled failures in rock. Easily import and update geometry and joint field data, and export geometries of the excavation, blocks, and block failure information.
• Integration with Other Rocscience Tools: RocTunnel3 seamlessly integrates with other Rocscience software like Dips and UnWedge, allowing for the import of joint locations, orientation data, and model geometry to fully define your model.
