eng.retaining-wall-stability Calculator
Calculates combined overturning, sliding, and bearing capacity factors of safety for a gravity or cantilever retaining wall. Retaining wall design requires simultaneous satisfaction of three failure modes — overturning, sliding, and bearing — with different safety factors for each.
Inputs
Wall Height M
Vertical measurement. For health calculators, typically standing height without shoes.
Base Width M
Horizontal extent perpendicular to the length.
Surcharge Kpa
Applied force or weight (N or kN). Divide into dead load (permanent) and live load (variable — people, wind, etc.).
Soil Angle Deg
Reference formula or conversion factor shown for context.
Wall Unit Weight Kn M3
Body or object weight. For health calculators, usually in kg or lbs.
Results
FOS overturning
Sample size or count used in the calculation.
FOS sliding
Sample size or count used in the calculation.
active earth pressure Ka
Reference formula or conversion factor shown for context.
total earth thrust Pa (kN/m)
Forward propulsive force generated by the engine or motor. Net thrust = gross thrust minus inlet momentum drag.
min FOS overturn
Sample size or count used in the calculation.
Rankine Ka = tan²(45-φ/2)
The position in an ordered list, from best to worst or lowest to highest.
