Description

Liquiter – Soil liquefaction analysis

LIQUITER is a software for the analysis and calculation of 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)

4 reviews for Soil liquefaction analysis – Liquiter

  1. Antonio Di Nardo (verified owner)

    Ottimo strumento di analisi ed interpretazione dei dati di campo. Di semplice utilizzo. Migliorerei la parte grafica in restituzione.

  2. FRANCESCO (verified owner)

    Ottimo software, per la determinazione del potenziale di liquefazione, lo consiglio molto

  3. Andrea (verified owner)

    Ottimo software l’unico aggiornato NTC 2018. Indispensabile per chi redige relazioni geologico-sismiche.

  4. MASSIMO FANTONI (verified owner)

    Ottimo software per la verifica liquefazione
