Grain Configuration Effect on Pore Water Pressure in Debris Flow
Frontiers in Earth Science, 2021 The generation and development of excess pore water pressure directly affects the grain interaction in debris flow, which can significantly reduce the friction strength and promote the movement of debris flow.

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.

Journal of the Civil Engineering Forum, 2023 Liquefaction is soil condition associated with the drastic increase in pore water pressure of uniform sandy soil due to an enormous earthquake. Therefore, this study aimed to investigate the correlation of liquefaction potential with excess pore water ...
