Behavior of Soil Undergoing Cyclic Undrained Loading
Dense sand has an increased resistance against liquefaction. Therefore, such densification as sand compaction pile, vibroflotation, and rod compaction are reliable mitigation measures against liquefaction. Densification is good also because its effects are permanently valid without maintenance efforts. compares the dilatancy of loose and dense sands schematically. Dense sand has a reduced possibility of volume contraction upon shear. Hence, it is less likely to liquefy.
