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.

Dynamic pore water pressure in saturated soil due to turbine engine’s vibration [PDF]

E3S Web of Conferences, 2023
The turbine engine that is operating will generate vibrations that are transmitted by the foundation into the soil layer. This causes the pore water pressure in the soil to increase, which causes the shear strength of the soil to decrease and can reduce ...
