Liquefaction Strength of Sands Subjected to Sustained Pressure
ABSTRACT Using two kinds of sands, a series of cyclic undrained triaxial tests was performed on loose and dense specimens subjected to different periods between 0.1 hour and 68 days of sustained pressure. At the same time, tests on specimens over-consolidated with an OCR of two or four were performed in order to compare the effects of long-term ...

Mitigation of liquefaction of saturated sand using biogas
Some recent studies have indicated that the liquefaction potential of saturated sand can be greatly reduced if the sand can be made slightly unsaturated. One way to reduce the degree of saturation of sand is to inject gas into sand.

Sand Liquefaction Through Volume Decrease Potential
ABSTRACT Cyclic triaxial shear tests were performed on granular materials with a variety of grain sizes and uniformity coefficients to determine the effect of grain composition on the liquefaction potential of cohesionless soils. In place of the conventional measure of relative-density as a density index the difference between the current and minimum

Static liquefaction of very loose sand-slag-bentonite mixtures
Static liquefaction is a highly destructive mechanism in the failure of soil deposits caused by a sudden loss of effective stress accompanied by vast deformations and a rapid build-up of pore water pressure that can cause soils to behave like liquids ...

The static cone penetration test (CPT) is an internationally used technique for potential evaluation of soil liquefaction in the world. The common method of CPT is based on the equivalent pure sand and only applicable to sand and low plastic fine-grained

Liquefaction Process of Sand During Cyclic Loading
ABSTRACT Both quick cyclic and slow cyclic shear tests are performed on saturated sand to investigate the process of liquefaction under the condition of constant mean principal stress. Special tests with varying amplitude of cyclic shear stress are also performed to estimate the change in excess pore water pressure during irregular cyclic loading ...

Effect of Cyclic Loading Frequency on Liquefaction Prediction of Sand
The frequency of ground motions during earthquakes is typically in the order of a few hertz. As the earthquake-induced liquefaction of soils is widely assessed by performing laboratory tests, it is necessary to consider various loading frequencies ...
