Cliq

Soil liquefaction assessment software from CPT/CPTU data.

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 CPT and CPTU data. The new 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).
