Numerical Analysis of an Upstream Tailings Dam Subjected to Pond Filling Rates
Applied Sciences, 2021 One of the challenges in upstream tailings dam projects is to ensure the allowable rate of deposition of tailings in the pond (i.e., pond filling rate) while maintaining the stability of the dam.

Effect of negative excess pore-water pressure on the stability of excavated slopes [PDF]
Géotechnique Letters, 2020 Generation of negative excess pore-water pressure (NEPWP) due to the excavation of saturated soils under undrained conditions and the dissipation that follows over time may result in different short- and long-term slope instability. The NEPWP generated due to excavation gradually decreases towards equilibrium or, in some cases, steady seepage.

Acceleration of Debris Flow Due to Granular Effect
Frontiers in Earth Science, 2021 Pore water pressure has been recognized as an important factor to enhance the mobility of debris flow moving in channel of very gentle slope. The creation and dissipation of pore water pressure are associated with interaction between grains.

Excess pore water pressure due to ground surface erosion [PDF]
Applied Mathematical Modelling, 2018 Abstract The Laplace transform is applied to solve the groundwater flow equation with a boundary that is initially fixed but that starts to move at a constant rate after some fixed time. This problem arises in the study of pore water pressures due to erosional unloading where the aquifer lies underneath an unsaturated zone.

Blast Liquefaction Test of Saturated Sand Foundations Disposed by a Drainage Rigid Pile
Shock and Vibration, 2022 Drainage rigid piles represent a commonly used antiliquefaction treatment for saturated sand foundations. Small-scale model tests on the liquefaction-resistant characteristics of drainage rigid piles subjected to blasting were conducted in this study ...

Prediction of Excess Pore Water Pressure of Reservoir Embankment on Soft Ground [PDF]
Journal of The Korean Society of Agricultural Engineers, 2008 A theoretical equation was proposed to consider the effect of ponding for the excess pore water pressure in agricultural reservoir on soft clay ground. The value of excess pore water pressure predicted using the proposed equation was compared to those predicted with the Terzaghi`s method and the finite difference method(FDM), respectively, for the ...
