Energy-Based Pore Pressure Generation Models in Silty Sands under Earthquake Loading

open access: yesGeosciences
During an earthquake, excess pore water pressure generation in saturated silty sands causes a reduction in shear strength and even liquefaction of the soil.

Insoluble polyelectrolyte and ion-exchange hollow fiber impregnated therewith [PDF]

open access: yes, 1977
The number of quaternary sites and ion exchange capacity of a polyquaternary, cross linked, insoluble copolymer of a vinyl pyridine and a dihalo organic compound is increased by about 15-35% by reaction of the polymer with an amine followed by ...

Stability Analysis of Coastal Sheet Pile Wall Considering Soil Weakening Induced by Earthquake Loading

open access: yesJournal of Marine Science and Engineering
A sheet pile wall is a widely used retaining structure in coastal and riverbank areas. In liquefiable soils, seismic activity can generate excess pore pressure, which not only increases the load on the sheet pile wall but also reduces the soil strength ...

Experimental investigation of wave-driven pore-water pressure and wave attenuation in a sandy seabed

open access: yesAdvances in Mechanical Engineering, 2016
Wave–seabed interaction has become a big concern of coastal researchers and engineers in the past decades as it may largely contribute to the seabed instability and failure of marine foundations.

Evolution of excess pore water pressures around monopiles subjected to moderate seismic loading

open access: yesSoil Dynamics and Earthquake Engineering
The sustained growth of the offshore wind sector is leading to the construction of offshore wind farms in highly seismic regions of the world. Hence, a large proportion of the potential sites may be exposed to liquefaction risk. Monopiles are directly affected by this phenomenon given their preference as a support system for offshore wind turbines over

CO2 injection into submarine sediments: disturbing news for methane-rich hydrates [PDF]

open access: yes, 2011
The production of natural gas via injection of fossil-fuel derived CO2 into submarine gas hydrate reservoirs can be an example of tapping a hydrocarbon energy source in a CO2-neutral manner.

Estimating Earthquake-Induced Pore Water Pressure: Hierarchy of Existing Methods

open access: yesGeosciences
The prediction of earthquake-induced excess pore water pressure is becoming a crucial step for liquefaction-related problems, such as the prediction of settlements, assessment of bearing capacity of shallow foundations, and efficiency of liquefaction ...
