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