Why it exists

Well-established methods for everyday geotechnical design.

A great many design and assessment questions — a footing, a wall, a cut, a slope — are answered by well-established methods. GeoTerva puts those methods within easy reach.

Low costMonthly or Annual access to every module. The first 7 days are free, to work with on screen.
On every deviceThe same modules in the browser of a phone, a tablet or a PC. Check a wall at the excavation, review it on a tablet, finish the report at the desk.
Nothing to installNo installation, no dongle, no licence server. Create an account and start: GeoTerva opens in any current browser.
Within reach of non-specialistsGeoTerva asks for the quantities an engineer has in hand and explains each one, so a complex calculation can be run — and understood — without being a specialist.

Built to be understood

Every module explains itself.

A calculation you can follow is a calculation you can check. In every module:

Info boxes at the inputsEach input is named and described. A “?” opens an explanation, with a figure where a figure helps.
A worked example to start fromEvery module opens on a worked example. Change the numbers and press Analyze.
The working, step by stepThe Calculations tab writes out every step with its numbers, so a result can be repeated by hand.
Warnings in plain wordsThe assumptions and the warnings are listed with the results: what the calculation took for granted and what it could not check.
Theory beside the calculationA Theory tab gives the method, its equations and its limits. The theory pages are free to read, with no sign-up.
A report to attachWord and PDF calculation reports with the drawings and the working, ready to go with a design.

Where it fits

The quick, checkable answer.

What it covers

Foundations: Bearing capacity, piles and the settlement under them.
Retaining & excavation: Earth pressure, retaining walls, sheet piles, braced cuts and surcharge loads.
Ground & stability: Stresses in the ground, slope stability and liquefaction.

Standard methods

Standard analytical and limit-equilibrium methods answer the design and assessment questions that most projects ask.

GeoTerva calculates; the engineer decides. Every result comes with its working so that it can be checked, and the responsibility for a design stays with the engineer.

Each module is tested against worked examples or independent hand calculations before it is released.
