Characterizing the Liquefaction Resistance of Aged Soils

Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008
The 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 ...

Liquefaction Resistance of a Silty Sand Deposit Subjected to Preshaking Followed by Extensive Liquefaction

Journal of Geotechnical and Geoenvironmental Engineering, 2016
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:

Evaluation of Liquefaction Resistance by in Situ Soundings

1996
Abstract For accurate evaluation of the cyclic strength of sand, recovery of high-quality undisturbed samples and testing in the laboratory would be the most reliable procedure. However, the sampling of sand samples from deposits below the ground water table is a costly operation and cannot be recommended for every occasion of ...

Liquefaction-Resistant Foundations for Residential Buildings

2013
On 4 September 2010 a Magnitude 7.1 earthquake struck the Canterbury region of New Zealand, centred 40km west of Christchurch and 10km deep, causing significant damage. On 22 February 2011 an aftershock of Magnitude 6.3 struck directly beneath the southern suburbs of Christchurch.

Effect of static shear on resistance to liquefaction

2010
The influence of initial static shear stress on undrained cyclic loading behavior of saturated Ottawa sand has been studied using the triaxial test. Improved sample preparation techniques and testing equipment were employed to obtain samples of uniform density and minimize the effect of sample disturbance.

Model prediction of cyclic liquefaction resistance of gassy soils

Acta Geotechnica
The 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.

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.
