Geotechnical Formulas

Geotechnical Formulas is a comprehensive reference app for civil and geotechnical engineers, students, and field professionals working with soil mechanics and foundation design.

The app covers seven core engineering categories:

- Soil Properties: Water content, unit weight, void ratio, relative density, Atterberg limits, permeability, and more.
- Effective Stress: Total stress, pore water pressure, effective stress, and capillary effects.
- Bearing Capacity: Terzaghi and general bearing capacity equations for shallow and deep foundations.
- Settlement: Immediate, consolidation, and secondary compression settlement calculations.
- Slope Stability: Factor of safety methods including the infinite slope model and Bishop's simplified method.
- Lateral Earth Pressure: Rankine and Coulomb active and passive earth pressures, at-rest conditions.
- Foundation Design: Pile capacity, group efficiency, and retaining wall analysis.

Each formula includes a clear explanation of variables, units, and applicable conditions. Built-in calculators let you enter values and compute results instantly without switching to a separate tool.

The app works entirely offline. No account is required, and no data is collected
