Abstract : in this paper, the efficient stress method is used as main means, while the railway engineering anti - earthquake design specification and the dynamic triaxial test are used as additional means. the authors analyze the ground layer liquefaction of shield tunnelling built on powder soil or fine sand, whose top plate is buried under two kinds of depth, and conclude that the liquefaction area is different with different buried depth. finally, the rational buried depth is proposed
