Anti-liquefaction Measure Research of Liquefied Layers of Shield Tunneling

About the question of layers' liquefaction of shield tunneling, the authors draw the conclusions through laboratory test and theoretical computation, that the liquefaction area of the bottom of shield tunneling will disappear and the liquefaction area of the top of shield tunneling will decrease if we change the buried depth of tunneling, or the layers are compacted, or the layers are injected by the number 425 silicate cement of 7 percent to 10 percent.
