Transition- and thin layer corrections for CPT based liquefaction analysis

Liquefaction potential of the subsoil is often assessed by performing an automated CPT based liquefaction triggering procedure. Due to a bias in the measured cone penetration resistance erroneous prediction of the liquefaction potential can be expected at the transition of soft, non-liquefiable and stiffer, liquefiable layers. This too is the case for relatively thin liquefiable layers interbedded in soft soil layers. A simple procedure is proposed that provides a solution to both issues in an automated liquefaction potential screening.
