Soil liquefaction analysis – Liquiter

Description

LIQUITER is a software for analysing and calculating soil liquefaction processes among the most complete and tested in the world.

Liquiter supports the following field tests for soil liquefaction analysis:

• • Standard Penetration Test (SPT);
  • Tests that calculate the shear waves velocities (Vs);
  • Cone penetration test (CPT);
  • Cone penetration test electric (CPTE );
  • Cone penetration test Piezocone (CPTU).
  • Grading curve
