Excess pore pressure generation during slurry deposition of gold tailings
International Journal of Mining, Reclamation and Environment, 2020Excess pore water pressure (PWP) in gold tailings, deposited in the laboratory in a settling column, was observed for various rates of deposition.

Pumping effect of rainfall-induced excess pore pressure on particle migration
Transportation Geotechnics, 2021Abstract Mud pumping in rail embankments has been observed in rainy seasons. In this study, a layered gravel-silt column was tested under cyclic loading to investigate the mud pumping mechanism caused by rainfall. The results show that liquid sloshing is more violent (larger velocity and wave height) with the water level higher. The pumping effect of

Study on Dissipation of Excess Pore Water Pressure of Clay
Applied Mechanics and Materials, 2012Dissipation of excess pore water pressure of saturation clay was discussed in the paper. Monotonic loading, unloading-reloading, and creep tests of one dimensional compression were performed to study the orderliness of dissipation of excess pore water pressure. In the drained consolidated tests, strain rate was changed step by step to check the effects

Identifying Consolidation Coefficient: Linear Excess Pore-Water Pressure
Journal of Geotechnical and Geoenvironmental Engineering, 2008Diagnostic curve methods are developed for simultaneously identifying consolidation coefficient, final settlement, and ratio of top and bottom excess pore-water pressures from observed settlements, in the case of linear excess pore-water pressure. Simple equations are also proposed for estimating consolidation coefficient and final settlement.

Excess Pore Pressure Measurement and Monitoring for Offshore Instability Problems
Offshore Technology Conference, 2007Abstract In situ pore pressure is one of the fundamental parameters required for assessing the strength and stability of geomaterials. In particular, identification of pore pressure regimes is necessary in geohazards studies. Offshore geological processes such as rapid sedimentation, minor slides, erosion, and fluid

Excess Pore Pressure During One-Dimensional Self-weight Consolidation
2018Consolidation of porous media under self-weight is a common process in nature environment and engineering facilities, such as sedimentation of soil particles in river delta and the consolidation of mine tailings during operation of tailings reservoir.

Effect of Biopolymer Treatment on Pore Pressure Response and Dynamic Properties of Silty Sand
, 2020Liquefaction is a phenomenon where the soil mass behaves like a liquid due to the rise in excess pore-water pressure, which results in the complete loss of shear strength.

Vertical Vibration of Pile in Vibration-Induced Excess Pore Pressure Field
Journal of Geotechnical and Geoenvironmental Engineering, 1997Vertical vibration of pile generates the cyclic shear in soil and can induce excess porewater pressure if the soil is submerged and cohesionless. The induced porewater pressure softens the soil and reduces the maximum skin friction allowed at the soil-pile interface.

Postcyclic behavior of low-plasticity silt with limited excess pore pressures
Soil Dynamics and Earthquake Engineering, 2013This paper investigates the postcyclic behavior of low-plasticity silt with excess pore pressure ratio (Ru) less than 1. The testing specimens were prepared from Mississippi River Valley (MRV) silt. Full and no reconsolidation were allowed after specimens were subjected to various excess pore pressure ratios due to cyclic loading in a cyclic triaxial ...
