In cohesionless soils, these waves create liquefaction that is followed by the compaction of the soil, and in cohesive soils, they create an increased amount of pore water pressure that is followed by the compaction of the soil.
2.
The resistance of the cohesionless soil to liquefaction will depend on the density of the soil, confining stresses, soil structure ( fabric, age and cementation ), the magnitude and duration of the cyclic loading, and the extent to which shear stress reversal occurs.
