Liquefaction is a common concern for geotechnical engineers in moderate-to-high seismic areas. Loose, non-plastic and saturated soils are most prone to liquefaction. Traditional approaches to decrease liquefaction are still widely used, however there are still major difficulties including restrictions on treatment area size, potential damage to sensitive structures, and environmental impact. Modern methods for liquefaction reduction include passive site remediation, microbial geotechnology and induced partial saturation. Air is far more compressible than water, hence unsaturation or partial saturation can help a soil deposit resist liquefaction. Even small volumes of gas bubbles in saturated soils can increase liquefaction resistance, especially around structures. Recently, bio-denitrification has been used to dissimulate nitrate to nitrogen gas as an alternative desaturation method. In this review article, Induced Partial Saturation (IPS), a modern liquefaction mitigation approach, and its methods: a) Microbially induced partial saturation (MIPS) or biogas and b) Air injection has been discussed in detail. This article examines how compositional and environmental elements affect soil gas bubble retention and treatment system efficiency. Overburden stress, soil density and fines concentration affect gas bubble retention and treatment efficiency. Gas loss from the soil surface, possibly from capillary invasion and crack opening, reduces treatment efficiency.
