Effects of Initial Shear Stress and Vibration Frequency on the Dynamic Pore-Water Pressure of Saturated Sands

open access: yesAdvances in Civil Engineering, 2018
The cyclic triaxial system is used to investigate the effects of confining pressure, initial shear stress, vibration frequency, and dynamic stress on the pore-water pressure characteristics of saturated sand in the Wenchuan area.

A semi-empirical model to predict excess pore pressure generation in partially saturated sand [PDF]

open access: yesE3S 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.

Liquefaction of Highly Saturated Sand Layer under Oscillating Water Pressure [PDF]

open access: yes, 1982
In this paper the vertical distribution of pore water pressure in the highly saturated sand layer under the oscillating water pressure are treated theoretically and experimentally. By the experiments it is shown that the water pressure acting on the sand

A Fluid-Solid Coupling Mathematical Model of Methane Driven by Water in Porous Coal

open access: yesGeofluids, 2018
The existence of the water-driven-methane effect in gassy coal has been verified by field tests and laboratory experiments. However, a water-driven-methane mathematical model that considers methane adsorption and desorption has not yet been established ...

Mechanism of pore pressure time lag for saturated clays

open access: yesYantu gongcheng xuebao
Time 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 ...
