Experimental study on the clogging effect of dredged fill surrounding the PVD under vacuum preloading

, 2020
Clogging effect surrounding prefabricated vertical drains (PVDs) is a typical problem when vacuum preloading is applied to a dredged fill foundation. A large-scale model test was designed to clarify the cause and mechanism of the clogging effect, and the

Apparent clogging effect in vacuum-induced consolidation of dredged soil with prefabricated vertical drains

, 2020
The improvement efficiency of a dredged slurry by vacuum preloading is greatly affected by the apparent clogging effect arising during the consolidation process, where the apparent clogging effect refers to the combined impacts of filter clogging and ...

Fines migration and pore clogging induced by single- and two-phase fluid flows in porous media: From the perspectives of particle detachment and particle-level forces

, 2020
Depressurization of hydrate-bearing sediments (HBS) is inevitably accompanied with sediment transport, not only structural host sediment itself but also fine particles, which can be a significant problem in producing gases from HBS, as demonstrated in ...

Effect of fertilizer solution concentrations on filter clogging in drip fertigation systems

, 2021
Drip irrigation using fertilizers is one of the commonly used methods to save fertilizer and minimize the impacts of fertilizer on the soil and the environment. However, the clogging issue of drip fertigation systems has been the major limitation and may
