Liquiter software is designed for soil liquefaction analysis and supports a wide variety of field tests. The results of the analysis are presented as: Safety Factor Soil Liquefaction / Probability of Soil Liquefaction; Cyclic mobility of clay; Liquefaction of sand and clay; CSR, variable CSR with depth from SHAKE results; Reconsolidation Settlement, Lateral Spreading; Residual Strength.
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)
• Grading curve
