Retaining Wall Sliding Calculator

Check sliding stability: FOS_slide = (ΣN·tanδ + c_a·B + P_p)/H_driving ≥ 1.5. Friction angle between concrete and soil δ = 2/3φ. Passive resistance from embedded key or footing depth.

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

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)

How It Works

Check sliding stability: FOS_slide = (ΣN·tanδ + c_a·B + P_p)/H_driving ≥ 1.5. Friction angle between concrete and soil δ = 2/3φ. Passive resistance from embedded key or footing depth

Each component has a specific meaning:

  • Embedded key or footing depth — The embedded key or footing depth recorded for the patient or scenario being assessed.

Note: Interpret the retaining wall sliding result against the clinical thresholds and context described above.

How to Use

Enter the embedded key or footing depth for the patient or scenario you are assessing. Check sliding stability: FOS_slide = (ΣN·tanδ + c_a·B + P_p)/H_driving ≥ 1.5. Friction angle between concrete and soil δ = 2/3φ. Passive resistance from embedded key or footing depth. Use the retaining wall sliding result to inform your clinical assessment.
