CPT liquefaction software CLiq is more advanced than the CPT section of the current LiqIT software and provides users an easy to use graphical environment specifically tailored for Cone Penetration Test data (CPT and CPTU). Our new soil liquefaction software addresses advanced issues such as cyclic softening in clay-like soils and thin layer/layer transition zone detection. CLiq provides results and plots for each calculation step, starting with the basic CPT data interpretation through to final plots of factor of safety, liquefaction potential index and post-earthquake displacements, both vertical settlement and lateral displacements. CLiq provides consistent output results by applying the state-of-the-art NCEER method (Youd et al, 2001) along with the calibrated procedures for post-earthquake displacements by Zhang et al (2002 & 2004). It also includes the latest assessment procedure developed by Robertson (2009) which is applicable to all soil type combining a check for cyclic liquefaction (sands) and cyclic softening (clays).
