Geotechnical Calculators

Computes ultimate and allowable bearing capacity of a shallow footing from derived bearing-capacity factors and a factor of safety. Use it for a first-pass foundation check.

Computes primary consolidation settlement and the time rate from soil compressibility and the stress increase. Use it to estimate foundation settlement.

Computes total stress, pore pressure and effective stress with depth, including a footing stress increase. Use it for geotechnical stress-profile calculations.

Computes active and passive earth pressure and the overturning, sliding and bearing checks for a retaining wall. Use it for a first-pass wall stability check.

Computes the factor of safety of a slope by the infinite-slope method, dry or with seepage. Use it for a first-pass slope stability check.

Classifies a soil to a Unified Soil Classification group symbol from its gradation and Atterberg limits. Use it to identify a soil for geotechnical work.
