How it works

Step 01

Enter your site parameters

Input CPT or SPT measurements, shear wave velocity, fines content, depth, groundwater table, and seismic loading (PGA, Mw). The tool accepts the full parameter set used in practice.

Step 02

Find the closest matches

The engine searches 8,634 case histories and returns the most geotechnically similar sites, ranked by similarity score. Retrieve the top 1, 3, 5, or 10 matches.

Step 03

Get AI-generated assessment

Each result set includes an AI engineering analysis with risk classification, liquefaction outcome (YES / NO / Unknown) for each matched site, and field remarks from original reconnaissance data.

Full parameter coverage

The tool accepts the complete set of parameters used in geotechnical liquefaction assessment.
