The density and fabric of sandy soil affect its resistance to liquefaction. Conventional sampling methods can disturb the soil fabric, so a new approach was needed. By conducting tests and measuring shear wave velocities, researchers found that soil particles without bonding effects show consistent liquefaction resistance trends. This means that the liquefaction resistance of sandy soil can be evaluated based on shear wave velocities measured in the field and in the lab.
