Characterizing the Liquefaction Resistance of Aged Soils
Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008The occurrence of liquefaction in soils is often evaluated using the simplified procedure originally proposed by Seed and Idriss based on in situ indices. Although numerous studies have been conducted to improve and extend this procedure, the effect of age on liquefaction resistance is still poorly understood and correction factors have not been ...

Micro electrical resistivity tomography for seismic liquefaction study
Journal of Applied Geophysics, 2020This paper presents a laboratory experiment where electrical resistivity tomographies (ERTs), joined to surface monitoring with Laser Scanner, were acquired in time-lapse on a sandbox, subjected to impulsive shear strain. The experiment is an attempt to monitoring the different stages characterizing the hydro-geophysical status of a soil prone to ...

AbstractThe effect of extensive liquefaction on the liquefaction resistance of heavily preshaken saturated silty sand is studied using a centrifuge experiment. The base of a 6-m homogeneous deposit was subjected to a total of 91 shaking events of different horizontal base accelerations and durations. Three event types were used in alternating patterns:

Increases in the strength and stiffness of sands with time have been widely reported. These temporal gains, or “aging effects”, are discernible from both in-situ penetration resistance and liquefaction resistance (CRR), where the rate of increase in CRR exceeds that inferred from in-situ penetration data.

LIQUEFACTION RESISTANCE OF OIL SAND TAILINGS
Mine tailings can be particularly prone to cyclic liquefaction because of their angular particle shapes, high saturation, and loose deposition. This has resulted in the liquefaction failure of several mine tailings dams in highly seismic regions around the world.openaire +1 more source
Model prediction of cyclic liquefaction resistance of gassy soils
Acta GeotechnicaThe resistance to liquefaction of soils can be significantly increased by slightly reducing the degree of saturation. Many experimental studies demonstrated that the augmented compressibility of the pore fluid mixture composed by entrapped bubbles within a continuous fluid phase reduces the amount of seismically induced excess pore water pressure.
