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