Slope Stability Calculator (Fellenius Method)

Compute factor of safety for circular slope failure using the Fellenius (Ordinary Method of Slices) with per-slice calculation of normal and shear forces.

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

Compute factor of safety for circular slope failure using the Fellenius (Ordinary Method of Slices) with per-slice calculation of normal and shear forces

Each component has a specific meaning:

  • Fellenius — The fellenius recorded for the patient or scenario being assessed.

Note: Interpret the fellenius slope stability result against the clinical thresholds and context described above.

How to Use

Enter the Fellenius for the patient or scenario you are assessing. Compute factor of safety for circular slope failure using the Fellenius (Ordinary Method of Slices) with per-slice calculation of normal and shear forces. Use the fellenius slope stability result to inform your clinical assessment.
