Effects of deviator strain histories on liquefaction of loose sand using DEM

, 2021
A series of undrained tests on loose sand with different pre-shearing histories are conducted in three-dimensional discrete element method (DEM) simulations.

Experimental study on the influence of cyclic loading frequency on liquefaction characteristics of saturated sand

Geotechnique
A series of undrained cyclic torsional shear tests were conducted to investigate the effect of cyclic loading frequency on the liquefaction characteristics of saturated sand using the hollow cylinder apparatus. The test results show that the dilative and

Influence of cementation on liquefaction of sands

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989
A study is reported which attempted to determine how cementation serves to resist liquefaction. Information on the relative influences of cementation and unit weight is reported since these two parameters sometimes produce similar effects. The study also determined what happens when soil is cemented in a nonhomogeneous manner, since this condition is ...

Small-strain shear modulus and liquefaction resistance of calcareous sand with non-plastic fines

Geotechnique
Incorporation of nonplastic fines can dramatically affect the liquefaction resistance and stiffness of sands. This study aims to evaluate the influence of nonplastic fines on the liquefaction resistance and small-strain shear modulus of calcareous sand ...

Liquefaction Screening—Non-plastic Silty Sands and Sands

2018
Liquefaction screening of sands and silty sands using cone penetration resistance is a difficult problem. The presence of silt particles among the sand grains in non-plastic silty soils alter the intergrain contact density and affect cyclic resistance, flow and consolidation characteristics, and cone resistance of the soil.

Shaking table tests on wall-type gravel and rubber drains as a liquefaction countermeasure in silty sand

Geotextiles and Geomembranes, 2021
In this paper, the seismic performance of wall-type gravel and rubber drains as a liquefaction countermeasure in silty sand has been addressed using a series of 1 g shaking table tests.

Sand Liquefaction: Inelastic Effective Stress Model

Journal of the Geotechnical Engineering Division, 1982
An effective stress numerical model for soil liquefaction, which provides interaction between shearing deformation and transient pore-water pressure development, is presented. Some attractive features of this one-dimensional model are the preservation of the inelastic soil character during shearing, the coupling between shear wave propagation and pore ...

Evaluating Liquefaction Strength of Partially Saturated Sand

Journal of Geotechnical and Geoenvironmental Engineering, 2004
A method is presented for evaluating the liquefaction strength of partially saturated sand using the compression wave velocity (P-wave velocity), a new indicator of saturation.

Static liquefaction of very loose sands

Canadian Geotechnical Journal, 1997
On presente les resultats d'une etude experimentale menee sur deux sables differents. Des essais triaxiaux en compression, draines et non draines, ont ete effectues sur du sable du Nevada a quatre indices de densite initiaux differents, soient 12, 22, 31 et 42%. Des essais semblables ont ete faits sur du sable d'Ottawa a un indice de densite initial de
