Excess pore water pressure behavior of saturated soft clay under cyclic confining pressure with different frequencies

Frontiers in Earth Science, 2023
The excess pore water pressure is main factor affecting the dynamic response of saturated soft clay under traffic loads. Recognize that, cyclic triaxial tests with and without cyclic confining pressure were carried out to study the development of excess ...

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.

Field monitoring of pore water pressure in fully and partly saturated debris flows at Ohya landslide scar, Japan [PDF]

Earth Surface Dynamics
The characteristics of debris flows (e.g., mobility, sediment concentration, erosion, and deposition of sediment) are dependent on the pore water pressure in the flows.
