CLiq 1.2 Description

"Soil liquefaction assessment software from CPT/CPTu data"

Editor: 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).

A unique 2D feature provides a means of creating colorful Contour maps of the overall liquefaction potential index (LPI) and post-earthquake vertical settlements in plan view thus allowing the user to visualize the spatial variation of liquefaction potential and settlements across a site. The variations of calculated post-earthquake settlements across a site allow estimates of differential settlements for a given site and design earthquake.

A Parametric analysis feature allows the user to vary both the earthquake magnitude and surface acceleration to evaluate the sensitivity of both the overall liquefaction potential index and post-earthquake settlements as a function of earthquake loading and results are presented in a 3D graphical form. you can free download CLiq 1.2 now.
