Acoustic emission induced by sand liquefaction during vibration loading [PDF]
Scientific Reports, 2022 The article deals with the study of poorly graded sand samples of different grain content subjected to liquefaction. The research results show the V-shaped behavior of the AE parameters that correspond to the three-stage sand behavior: Phase A is ...

Post-liquefaction reconsolidation of sand. [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 Loosely packed sand that is saturated with water can liquefy during an earthquake, potentially causing significant damage. Once the shaking is over, the excess pore water pressures that developed during the earthquake gradually dissipate, while the ...

Sand liquefaction in simple shear tests
E3S Web of ConferencesLiquefaction is a phenomenon marked by a rapid loss of soil strength and stiffness, which generally occurs in loose saturated sandy deposit during earthquake because of the generation of excess pore water pressure. Several experimental researches concluded that liquefied soil behaves as a fluid during ground movement, but after the earthquake motion ...

Effect of Cyclic Loading Frequency on Liquefaction Prediction of Sand
Applied Sciences, 2020 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 ...

Liquefaction Behavior of Bushehr Coastal Carbonate Sand [PDF]
Journal of Hydraulic Structures, 2022 Over the past few years, liquefaction phenomena have always been one of the challenging issues in geotechnical engineering. The occurrence of liquefaction is due to cyclic tensions resulting from zero effective stress in the soil mass.

Constitutive modelling of fabric effect on sand liquefaction
Journal of Rock Mechanics and Geotechnical Engineering, 2023 Sand liquefaction under static and dynamic loading can cause failure of embankments, slopes, bridges and other important infrastructure. Sand liquefaction in the seabed can also cause submarine landslides and tsunamis.
