When a body of cohesionless soil is saturated, water fills the pore spaces between  each particle.

当无粘性土壤饱和时，水会填充每个颗粒之间的孔隙空间。

Liquefaction happens when soil experiences  an applied stress, like an earthquake, that causes it to behave like a liquid, and it  mostly happens in cohesionless soils - those where the grains don't stick together, such as sand.

当土壤受到外加应力（例如地震）时， 液化就会发生，导致其表现得像液体一样，并且它主要发生在无粘性土壤中 - 颗粒不粘在一起的土壤，例如沙子。
