Features of the module

Need to evaluate the risk of soil liquefaction from your penetrometric data?

Websprint© allows you to evaluate the liquefaction hazard of soils subjected to seismic loads using different semi-empirical methods recommended in France and internationally.

With this module for soil liquefaction risk evaluation, Websprint© is the only software incorporating the 4 main methods, based on in situ tests, for the determination of soil liquefaction potential, namely: SPT, CPT, PANDA® and GRIZZY® dynamic penetrometers (DPSH) and wave velocity (Vs).

With Websprint©, once you have entered the characteristics of the site, you can :

  • define your calculation model: geographical, seismic, geological and project design data.
  • carry out analyses based on the processing of dynamic penetration soundings (PANDA®, GRIZZLY®) but also CPT(u), SPT and shear wave velocity (Vs)
  • use the integrated assistant (EUROCODE 8) for the seismicity of the site, and the various calculation methods (NCEER, Idriss & Boulanger…)
  • use a method specially designed for Tailings Dams
  • calculate the safety factor FS against the liquefaction phenomenon.
  • calculate the post-liquefaction settlements of saturated soils from different methods.
  • evaluate the liquefaction potential index (LPI).
  • generate a test report with all input data and calculation assumptions as well as the graphical representation of the analysis results.

In Websprint©, a simplified procedure for soil liquefaction risk evaluation has also been implemented.
