Please elaborate on liquefaction calculation?

Question

Accepted Answer

Liquefaction calculation involves determining the potential for soil to lose strength and behave like a liquid during an earthquake.

Liquefaction occurs when loosely packed, water-saturated soils lose strength due to increased pore water pressure during seismic shaking.
Calculations involve assessing factors such as soil type, density, saturation, and earthquake intensity to predict liquefaction potential.
Methods like the Standard Penetration Test (SPT) and Cone Penetration Test (CPT) are used to gather data for liquefaction analysis.
Engineers use empirical correlations and numerical modeling to estimate liquefaction susceptibility and potential consequences.
Mitigation measures may include soil improvement techniques, such as compaction grouting or deep soil mixing, to reduce liquefaction risk.
