Effects of Excess Pore Pressure Redistribution in Liquefiable Layers

Journal of Geotechnical and Geoenvironmental Engineering
Existing simplified procedures for evaluating soil liquefaction potential or for estimating excess pore pressures during earthquakes are typically based on undrained cyclic tests performed on saturated soil samples under controlled loading and boundary conditions.

Excess pore water pressure and its impact

Japanese Geotechnical Society Special Publication, 2016
This paper presents about the high level of excess pore water pressure. The high excess pore water pressure was monitored during pile driving work at saturated stiff to hard soil layer of Pleistocene.

Excess pore water pressure generation in fine granular materials under undrained cyclic triaxial loading

International Journal of Geo-Engineering, 2023
Understanding the mechanism of excess pore water pressure generation in subgrades is essential for not only designing but also further maintenance purposes.

Finite-hillslope analysis of landslides triggered by excess pore water pressure: the roles of atmospheric pressure and rainfall infiltration during typhoons

Natural Hazards and Earth System Sciences, 2022
. Landslides are often triggered by catastrophic events, among which earthquakes and rainfall are the most depicted. However, very few studies have focused on the effect of atmospheric pressure on slope stability, even though weather events such as ...

The Basal Friction Coefficient of Granular Flows With and Without Excess Pore Pressure: Implications for Pyroclastic Density Currents, Water‐Rich Debris Flows, and Rock and Submarine Avalanches

Journal of Geophysical Research: Solid Earth, 2020
Numerous large‐scale geophysical flows propagate with low‐apparent basal friction coefficients, but the source of such phenomenology is poorly known. Motivated by scarce basal friction data from natural flows, we use numerical methods to investigate the ...

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.

Field Test of Excess Pore Water Pressure at Pile–Soil Interface Caused by PHC Pipe Pile Penetration Based on Silicon Piezoresistive Sensor

Italian National Conference on Sensors, 2020
Prestressed high-strength concrete (PHC) pipe pile with the static press-in method has been widely used in recent years. The generation and dissipation of excess pore water pressure at the pile–soil interface during pile jacking have an important ...

Constitutive Model of Lateral Unloading Creep of Soft Soil under Excess Pore Water Pressure

Mathematical Problems in Engineering, 2020
Presented in this paper is a study on the lateral unloading creep tests under different excess pore water pressures. The marine sedimentary soft soil in Shenzhen, China, was selected in this study.

Experimental insights into consolidation rates during one-dimensional loading with special reference to excess pore water pressure

Acta Geotechnica, 2020
Consolidation rate has significant influence on the settlement of structures founded on soft fine-grained soil. This paper presents the results of a series of small-scale and large-scale Rowe cell consolidation tests with pore water pressure measurements

An Arbitrary Lagrangian Eulerian (ALE) finite difference (FD)‐SPH depth integrated model for pore pressure evolution on landslides over erodible terrains

International journal for numerical and analytical methods in geomechanics (Print), 2022
Entrainment of saturated bed material increases the mobility of fast landslides. The distribution of excess pore pressures changes in the body of the landslide, as the material entering it has much lower effective confining stresses which results on much
