Pore-water pressure changes during soil liquefaction

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1976
An analytical procedure is presented for evaluating the general characteristics of pore-water pressure buildup and subsequent dissipation in sand deposits both during and following a period of earthquake shaking. It is shown that in layers of fine sand, excess hydrostatic pressures may persist for an hour or more after an earthquake.

Pore water pressure sensor for landslide prediction

2015 IEEE SENSORS, 2015
The paper presents a cost effective pore water pressure sensor (PWP) for landslide prediction, based on an integrated silicon pressure sensor. The sensor can be associated with a landslide sensor or can work independently. The aim of the landslide sensor is to detect the wetting condition and the tiny displacements of the ground.

Pore-Water Pressures Induced by Pile Driving

Journal of the Geotechnical Engineering Division, 1979
In a recent pile-load testing program carried out by Ontario Hydro, steel H-piles were driven near Pickering , Ontario, and later tested to determine their uplift capacity in connection with the design of tower foundation for a new transmission line.

Pore Water Pressure Response during Tsunami Loading

Journal of Geotechnical and Geoenvironmental Engineering, 2020
AbstractTsunamis induce excess pore water pressure gradients in coastal sediment beds. The excess pore water pressure gradient induced during tsunami loading along with the shear stress caused by t...

Wireless Mid-height Pore Water Pressure Sensor

Geotechnical Testing Journal, 2022
Abstract The triaxial apparatus is one of the most widespread testing devices used by geotechnical laboratories for identifying parameters characterizing soil strength and stiffness behavior. In order to do so, the triaxial apparatus has the ability to measure a number of key parameters, among which the measurement of axial force, axial ...

Pore water pressure in natural slopes

International Journal for Numerical and Analytical Methods in Geomechanics, 1981
AbstractEstimating subsurface pore water pressures in natural slopes along the periphery of rivers and reservoirs for future conditions, created by the operational requiremets to meet increases in energy demand from the observed data of the past and present, operations, is possible with the use of a mathematical model.

Movement of Pore Water, and Abnormally High Pore Pressures

1981
The distinction between ground water and pore water may not be very logical, but it has the merit of distinguishing the readily-exploitable fresher pore water near the surface from the brackish to salty water in the pore spaces of most sedimentary rocks at greater depth.
