Initial Distribution of Average Excess Pore Water Pressure Due to a Trapezoidal Load

open access: yesSoils and Foundations, 1974
A numerical integration procedure is used to evaluate the equations which give the initial distribution of excess pore water pressure in a subsoil due to a trapezoidal surface load, such as a highway embankment, and a series of curves are provided for a broad range of geometrical variations.

Changes in excess pore water pressure in soft ground under multi-factor influences coupled with positive and negative pressure

open access: yesShuiwen dizhi gongcheng dizhi
Vacuum stacking joint pre-compression method is widely used to reinforce soft ground. During the preloading process, a coupled mechanism involving positive and negative pore-water pressures develops within the soil, and the reinforcement performance is ...

Excess pore water pressure generation in crushed and fine granular materials under cyclic traffic loads

open access: yes, 2023
Excess pore water pressure can develop in subgrades of railway and pavement substructures due to cyclic loading from heavy traffic, leading to the migration of fine particles into upper layers.

Accumulation of Pore Pressure in a Soft Clay Seabed around a Suction Anchor Subjected to Cyclic Loads

open access: yesJournal of Marine Science and Engineering, 2019
A suction anchor is an appealing anchoring solution for floating production. However, the possible effects of residual pore pressure can be rarely found any report so far in term of the research and design.

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Excess pore water pressure generation in fine granular materials under cyclic loading -A laboratory study

open access: yes, 2021
Excess pore water pressure can be generated in subgrades of both railway and pavement sub-structures under cyclic loading caused by heavy traffic. When saturated subgrades are subjected to cyclic loading, excess pore water pressures accumulate over time ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Shear Strength Reduction Due to Excess Pore Water Pressure [PDF]

open access: yes, 2001
Earthquake shaking causes the pore water pressure inside the soil mass to increase rabidly within a short period of time as seconds. As a result, the shear strength of the soil could be reduced significantly.
