Aiming at the defects that the lateral pressure coefficient K₀ is mostly assumed to be constant by engineering experience in practice and in numerical analysis, systemic tests of K₀ consolidation on the shallow gassy sand to identify and obtain its value of K₀ were carried out. The results show that K₀ of the unsaturated gassy sand is not fixed value, and soil structure, moisture content and density all affect it. Its value increases with the rising of moisture content and decreases with the increase of density. The density of gassy sand has more significant impact on the value of K₀ relative to the moisture content. Value of K₀ obtained in loose and saturation state of gassy sand is inclined to conservativeness and safety in the engineering design.
