Liquefaction and Displacement of Saturated Sand Under Vertical Vibration Loading
, 2004 In order to investigate the influence of the vertical vibration loading on the liquefaction of saturated sand, one dimensional model for the saturated sand with a vertical vibration is presented based on the two phase continuous media theory.

Analysis of the Shaft Resistance of Nondisplacement Piles in Sand [PDF]
, 2008 The paper examines, using numerical modelling, the problem of the limit shaft resistance of non-displacement piles installed in sands. The modelling makes use of an advanced, two-surface-plasticity constitutive model.

CYCLIC PRESSUREMETER LOADING AND LIQUEFACTION PROPERTIES OF SANDS
SOILS AND FOUNDATIONS, 2003 Based on a series of cyclic cavity expansion tests carried out on a thick hollow cylinder apparatus (HCC) and on mini-pressuremeter tests performed in a calibration chamber, a method is proposed to establish a reliable correlation between the result of a "reference" cyclic expansion test carried out in a sand, in terms of cavity volume accumulation ...

Repetitive Liquefaction at a Gravelly Site and Liquefaction in Overconsolidated Sands
Soils and Foundations, 1996 Repetitive liquefactions in angular and subangular gravels from an alluvial fan, in the case of two earthquakes with accelerations lower than that of a former which had caused liquefaction some months before, are described. The liquefaction took place from the surface, down to a depth of approximately 10 m.

A Microscopic Definition of Liquefaction for Sand
Procedia Earth and Planetary Science, 2012 AbstractTraditional theoretical and experimental investigations of the mechanical behavior of granular media such as sand are restricted by the limited quantitative information about what actually happens internally. The discrete element method (DEM) was developed as a technique to examine the micromechanics of granular media for this purpose.

The Liquefaction and Displacement of Highly Saturated Sand under Water Pressure Oscillation
, 2004 In order to investigate the characteristics of water wave induced liquefaction in highly saturated sand in vertical direction, a one-dimensional model of highly saturated sand to water pressure oscillation is presented based oil the two-phase continuous ...

Ensemble‐based soil liquefaction assessment: Leveraging CPT data for enhanced predictions
Civil Engineering Design, Volume 7, Issue 1, Page 23-35, March 2025.Abstract This study focuses on predicting soil liquefaction, a critical phenomenon that can significantly impact the stability and safety of structures during seismic events. Accurate liquefaction assessment is vital for geotechnical engineering, as it informs the design and mitigation strategies needed to safeguard infrastructure and reduce the risk ...

Liquefaction Resistance of Sand Deposit Improved with Sand Compaction Piles
Soils and Foundations, 2003 ABSTRACT This paper reports results of in-situ tests and undrained cyclic shear tests on high-quality undisturbed samples obtained by the in-situ freezing method at three sites where foundation soils had been improved with sand compaction piles. Triaxial specimens obtained from the frozen samples were fully saturated in the triaxial cell and then ...
