Abstract:Background:The so-called smear zone is a disturbed zone developed in soil during prefabricated vertical drainage (PVD) installation using a mandrel. There are 2 main parameters typically used to characterize the smear zone. First, the extent ratio signifies the extent of the soil damage due to mandrel penetration; and second, the permeability ratio κ represents the degree of disturbance to the soil permeability within the smear zone.
