A semi-empirical model to predict excess pore pressure generation in partially saturated sand [PDF]
E3S Web of Conferences, 2020 Past studies revealed that excess pore pressure generation due to cyclic loading is highly governed by induced strains, volumetric deformation potential of soil, number of cycles, and bulk stiffness of pore fluid.

Mechanism of pore pressure time lag for saturated clays
Yantu gongcheng xuebaoTime lag of pore pressure often occurs during oedometer consolidation of saturated clays. After applying loading, the pore pressure measured at the base of specimens increases up to the maximum and then decreases with the increase in consolidation time ...

Effect of hydrogel particle additives on water-accessible pore structure of sandy soils: A custom pressure plate apparatus and capillary bundle model [PDF]
, 2013 To probe the effects of hydrogel particle additives on the water-accessible pore structure of sandy soils, we introduce a custom pressure plate method in which the volume of water expelled from a wet granular packing is measured as a function of applied ...

Fouling mechanisms in constant flux crossflow ultrafiltration [PDF]
, 2019 Four fouling models due to Hermia (complete pore blocking, intermediate pore blocking, cake filtration and standard pore blocking), have long been used to describe membrane filtration and fouling in constant transmembrane pressure (ΔP) operation of ...
