How hard does the soil push, and will the wall tip or slide? Set the soil properties and geometry to see the active earth pressure and stability factors.

earth pressure & stability
Controls
Presets
Rankine theory gives the active earth pressure behind a wall from the coefficient Ka = tan²(45−φ/2). The soil pushes with a triangular pressure resultant Pa acting at one-third the height. The wall must resist overturning and sliding with adequate factors of safety. Educational tool, not a geotechnical design.

How it works
Rankine earth-pressure theory gives the active pressure coefficient Ka = tan²(45−φ/2), producing a triangular pressure whose resultant acts at one-third the wall height. The wall must resist both overturning about its toe and sliding along its base with adequate factors of safety. Educational tool, not a geotechnical design.
