HOW THIS VERIFICATION WORKS

Step 1: Compute intersection line orientation of two discontinuity planes — engineering workflow step. Follow the documented method for manual execution.
Step 2: Assess wedge daylighting and sliding potential against slope face and friction cone — engineering workflow step. Follow the documented method for manual execution.

This tool coordinates 0 validation steps and 2 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 intersection line orientation of two discontinuity planes

Manual Workflow

ρ = arcsin(|n₁ × n₂|), where nᵢ = [sinδᵢ cosαᵢ, sinδᵢ sinαᵢ, cosδᵢ] are unit normals; the magnitude of the cross product yields sin(ρ), giving the plunge of the intersection line.

Step 2: Assess wedge daylighting and sliding potential against slope face and friction cone

Manual Workflow

1. Compute angular distance between intersection line trend/plunge and slope face pole: if ≤ 90°−δ_f → daylighting possible. 2. Compute acute angle γ between intersection line and third plane: γ = 90° − |ρ − δ₃| if trends align within ±20°, else use vector dot product. If γ < φ → sliding feasible. Wedge is kinematically admissible iff both conditions hold.

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 intersection line orientation of two discontinuity planes (Step 1).
For calculation of Assess wedge daylighting and sliding potential against slope face and friction cone (Step 2).
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.
