Study of the Permeability of Foam Conditioned Soils with Laboratory Tests [PDF]

open access: yes, 2010
EPB tunneling requires that the excavated soil has a plastic and pulpy behavior to be able to apply a stabilizing pressure to the face, but it should also be impervious to counteract filtration forces that could develop ahead of the face.
