Liquefaction and Postliquefaction Behavior of Sand

Journal of Geotechnical Engineering, 1995
The static undrained behavior of saturated sand is shown to be dilative in triaxial compression, even in the loosest deposited state. However, the behavior in triaxial extension is contractive for relative densities of up to 60%, implying a profound anisotropy of response to undrained loading.

Liquefaction potential of reinforced sand

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1994
Abstract A simple stress-controlled cyclic triaxial testing system developed for liquefaction testing is described. Using this system, a series of cyclic undrained triaxial tests were performed on sands with different densities and with different types of reinforcements to investigate the effect of reinforcement in enhancing resistance to ...

Statistical Analysis of Sand Liquefaction

Journal of the Geotechnical Engineering Division, 1981
A consistent set of stochastic models is developed for the liquefaction resistance of a homogeneous mass of sand, such as a laboratory sample or small element of in situ material. A probabilistic model for liquefaction in the laboratory for undrained simple shear tests is developed first.

Liquefaction and post-liquefaction resistance of sand reinforced with recycled geofibre

Geotextiles and Geomembranes, 2022
Abstract The present study provides an insight into the effect of recycled carpet fibre on the mechanical response of clean sand as backfill material subjected to monotonic loading and cyclic loading as well as post-liquefaction resistance of both unreinforced and carpet fibre reinforced soils.

Cyclic liquefaction strength of sands

Earthquake Engineering & Structural Dynamics, 1979
AbstractThrough an energy approach, a model is proposed to predict the cyclic liquefaction strength of saturated sands in terms of their static shear strengths. Plots of cyclic liquefaction strength versus relative density and also versus modified standard penetration resistance are presented for various uniformity coefficients and different numbers of

Seismic Response and Liquefaction of Sands

Journal of the Geotechnical Engineering Division, 1976
An effective stress analysis has been developed for determining the dynamic response of horizontal saturated sand deposits to earthquake motions consisting of vertically propagating shear waves. A hyperbolic stress-strain law is used for sands in shear and during the earthquake motions the modulus and damping properties of the sands are modified ...

Specimen Preparation and Liquefaction of Sands

Journal of the Geotechnical Engineering Division, 1974
This note presents results of a liquefaction testing program performed on three different sands, specimens of which were prepared by two common but different methods. Results demonstrate that specimen preparation methods significantly affected the liquefaction behavior.

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.

Liquefaction resistance of sand reinforced with geosynthetics

Geosynthetics International, 2008
This paper describes an investigation into the performance of geosynthetics in enhancing the resistance to liquefaction of medium dense (Dr = 50%) sand deposits. Cyclic torsional shear tests were carried out on 99 laboratory test specimens under a confining pressure of 98 kPa and a loading frequency of 0.1 Hz.

Static liquefaction of sand in plane strain

Canadian Geotechnical Journal, 2007
Experimental results on the static liquefaction behaviour of sand under plane-strain conditions are presented in this paper. Undrained tests on very loose sand under both plane-strain and axisymmetric conditions were conducted and the results compared.
