Influence of Excess Pore Pressure Development on Inertial Pile Response

2023
The behavior of piles in submerged and liquefiable sandy soils under earthquake loads attracted attention of researchers since 1980s. In this study, behavior of soil surrounding piles in such soils was investigated. In the study, response of the piles under inertial loads was considered, and it was assumed that the soil was in passive terms of during ...

Excess pore pressure generation during slurry deposition of gold tailings

International Journal of Mining, Reclamation and Environment, 2020
Excess 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, 2021
Abstract 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, 2012
Dissipation 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, 2008
Diagnostic 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, 2007
Abstract 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

2018
Consolidation 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.

Vertical Vibration of Pile in Vibration-Induced Excess Pore Pressure Field

Journal of Geotechnical and Geoenvironmental Engineering, 1997
Vertical 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, 2013
This 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 ...

Experimental approach for assessing dissipated excess pore pressure-induced settlement

Canadian Geotechnical Journal
Upon dynamic loading, saturated soils lose their strengths and undergo deformations resulting in volumetric-induced settlements that vary according to the excess pore pressure generation and dissipation variations. Traditionally, these settlements have been evaluated using standard charts based on one soil type and its relative density (RD). To assess
