PROJECT INPUTS
Runnable deterministic steps: 0 / 3. Enter the project conditions used by this verification workflow. Prefilled values (5/7 inputs) are demonstration inputs, not recommended design values.
Step 1: Compute Fisher concentration parameter κ from angular dispersion of unit normals — κ = 1 / (1 − √R̄), where R̄ is the mean resultant length of unit normal vectors computed from dip/dip_direction pairs; derived from Fisher distribution maximum likelihood estimator for small-κ approximation.
Step 2: Compute fault damage zone width using empirical power-law relation with fault throw — D_dz = T^0.65 × (1.2 + 0.8×(100−RMR)/100) × (1.0 + 0.3×FA), where FA = 0 (inactive), 1 (quaternary), or 2 (historical); calibrated to global fault damage zone datasets (Faulkner et al., JGR 2010).
Step 3: Compute risk-weighted intersection frequency per kilometer — RWIF = (Σᵢ(HPSᵢ × KIFᵢ) / L) × 1000, where HPSᵢ is hydraulic potential score of i-th intersected domain, KIFᵢ = 1.0 (planar slide feasible), 1.5 (wedge slide feasible), or 2.0 (both + high aperture), and L is tunnel length in meters.

Engineering Verification Summary
HOW THIS VERIFICATION WORKS
Step 1: Compute Fisher concentration parameter κ from angular dispersion of unit normals — engineering workflow step. Follow the documented method for manual execution.
Step 2: Compute fault damage zone width using empirical power-law relation with fault throw — engineering workflow step. Follow the documented method for manual execution.
Step 3: Compute risk-weighted intersection frequency per kilometer — engineering workflow step. Follow the documented method for manual execution.
This tool coordinates 0 validation steps and 3 calculation steps. The overall engineering decision uses ALL_REQUIRED_VALIDATION_PASS aggregation: only validation steps contribute to the pass/fail outcome; calculation steps produce data only.
METHODS & EQUATIONS
All formulas are resolved from canonical runtime definitions and executed deterministically by the client-side engine.
Step 1: Compute Fisher concentration parameter κ from angular dispersion of unit normals
Manual Workflow
κ = 1 / (1 − √R̄), where R̄ is the mean resultant length of unit normal vectors computed from dip/dip_direction pairs; derived from Fisher distribution maximum likelihood estimator for small-κ approximation.
Step 2: Compute fault damage zone width using empirical power-law relation with fault throw
Manual Workflow
D_dz = T^0.65 × (1.2 + 0.8×(100−RMR)/100) × (1.0 + 0.3×FA), where FA = 0 (inactive), 1 (quaternary), or 2 (historical); calibrated to global fault damage zone datasets (Faulkner et al., JGR 2010).
Step 3: Compute risk-weighted intersection frequency per kilometer
Manual Workflow
RWIF = (Σᵢ(HPSᵢ × KIFᵢ) / L) × 1000, where HPSᵢ is hydraulic potential score of i-th intersected domain, KIFᵢ = 1.0 (planar slide feasible), 1.5 (wedge slide feasible), or 2.0 (both + high aperture), and L is tunnel length in meters.
UNDERSTANDING THE RESULTS
PASS
A proven validation criterion passed. The engineering input satisfies the deterministic threshold.
FAIL
A proven validation criterion failed. The engineering input does not satisfy the deterministic threshold.
CALCULATED
A deterministic calculation completed, but no acceptance criterion exists for this step. CALCULATED does NOT mean PASS.
RESULT NOT VALID
Runtime executed but engineering validity requirements were not met.
INCOMPLETE
Required inputs or workflow steps are incomplete.
The overall decision reflects only validation steps. Calculation steps produce numerical results without pass/fail claims.
WHEN TO USE THIS TOOL
When deterministic Borehole Optical Televiewer engineering verification is needed for project-specific conditions.
For calculation of Compute Fisher concentration parameter κ from angular dispersion of unit normals (Step 1).
For calculation of Compute fault damage zone width using empirical power-law relation with fault throw (Step 2).
For calculation of Compute risk-weighted intersection frequency per kilometer (Step 3).
For deterministic pre-checks before formal engineering review or submission.
When NOT to use this tool: This tool does not replace laboratory testing, formal engineering analysis by a licensed professional, or code-compliance certification. It performs deterministic threshold comparison and calculation only.
