Liquefaction The term 'Liquefaction' as it applies to the area of reclamation can be defined as ' When a solid form is turned into a liquid form. During an earthquake, low density materials act like water and lose their supporting strength. A condition whereby soil undergoes continued deformation at a constant low residual stress or with low residual resistance, due to the buildup and maintenance of high pore water pressures, which reduces the effective confining pressure to a very low value. Pore pressure buildup leading to liquefaction may be due either to static or cyclic stress applications, and the possibility of its occurrence will depend on the void ratio or relative density of a cohesionless soil and the confining pressure'.
