Soil Nail Length Design Calculator

Estimate soil nail length and pullout capacity for soil nail wall design using FHWA geotechnical design approach with bond strength, nail spacing, and failure surface geometry.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Estimate soil nail length and pullout capacity for soil nail wall design using FHWA geotechnical design approach with bond strength, nail spacing, and failure surface geometry

Each component has a specific meaning:

  • FHWA geotechnical design approach — The fhwa geotechnical design approach recorded for the patient or scenario being assessed.

Note: Interpret the soil nail length result against the clinical thresholds and context described above.

How to Use

Enter the FHWA geotechnical design approach for the patient or scenario you are assessing. Estimate soil nail length and pullout capacity for soil nail wall design using FHWA geotechnical design approach with bond strength, nail spacing, and failure surface geometry. Use the soil nail length result to inform your clinical assessment.
