Applies to soils below phreatic level submitted to seismic acceleration.

This function verifies liquefaction for cohesionless soils (Robertson & Wride 1997 – CNR – GNDT) Safety factor related to various seismic zones I II III IV cat.

 

N.B. Liquefaction is absent for Fs >= 1,25, possible for Fs = 1,0 – 1,25 and very probable for Fs< 1.
