Design Tip: Enter your parameters and click Calculate to get started.

Rankine Theory: Assumes a frictionless wall and considers only the active earth pressure.

Coulomb Theory: Accounts for wall friction and backfill slope angle.

Sliding: Factor of safety ≥ 1.5

Overturning: Factor of safety ≥ 2.0

Bearing Capacity: Maximum pressure ≤ Allowable bearing pressure
