Calculators

Geotechnical Calculators

Fast, stateless engineering checks — SPT corrections, correlations, stress-influence factors, settlement, and more — each with the full equation rendered.

What it does

The Calculators are a collection of quick, single-shot tools for everyday geotechnical checks — no project setup required. Enter a few values and get an answer with the governing equation rendered in full.

Tools cover SPT N-value corrections, OCR and modulus correlations, stress-influence factors, single-layer settlement, bearing pressure, and sliding capacity, among others.

Each calculator shows its formula and substituted values, so the result is transparent and easy to drop into a calculation package.

Methodology

Coduto, Foundation Design, and standard correlations

Capabilities

  • SPT N-value corrections (overburden, energy, rod)
  • OCR and modulus correlations
  • Stress-influence factors (Boussinesq)
  • Single-layer settlement
  • Bearing-pressure and sliding-capacity checks
  • Fully rendered equations with substituted values
  • Stateless — no project or setup to run
  • Copy-ready output for calculation packages
