Most Powerful Soil Liquefaction Analysis Software – GeoLiqu


GeoLiqu
is the only soil liquefaction analysis software on the market capable of calculating liquefaction potential, seismic settlement (dry and saturated) and lateral spreading based on standard penetration test (SPT) data, cone penetration test (CPT) data and shear wave velocity (Vs) data profiles.

GeoLiqu is based on state-of-the-art theory and methods with up-to-date references.
