Liquefaction check¶

For each layer is viewed the liquefaction check with the method proposed by the CNR (Italian National Research Center) and suggested by GNDT (Italian National Group for the Defence against Earthquakes). The verification is performed only in the presence of seismic acceleration, cohesionless soils under GWT. The method CNR-GNDT – Tokimatsu and Yoshimi (1983).

The liquefaction resistance has the following expression
