Post-liquefaction reconsolidation of sand [PDF]

open access: yesProceedings 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 surface of the soil settles, in a process called post-liquefaction reconsolidation.

A constitutive model considering post-liquefaction deformation based on the logarithmic skeleton curve

open access: yesRock and Soil Mechanics, 2021
Most of the constitutive model for liquefaction analysis cannot simulate the large post-liquefaction deformation of saturated sand, and there is little research on the nonlinear time-domain large deformation constitutive relationships suitable for ...

Centrifuge shaking table tests on evolution mechanism of sand mesostructure during earthquake liquefaction

open access: yesYantu gongcheng xuebao, 2022
The existing studies demonstrate that the history of earthquake liquefaction is an important factor affecting the liquefaction resistance of sand. The researchers think the intrinsic mechanism of these effects is the generation of stable or unstable sand

Liquefaction test and seismic load simulation of saturated sand subgrade with different salt contents

open access: yesFrontiers in Earth Science, 2023
On the basis of the highway subgrade construction of North Hobson Salt Lake mining area in Qinghai Province, the soil samples of high saline saturated sand adjacent to the salt lake were remolded, and four types of saturated sand containing 0%, 10%, 20%,

Seismic Damage and Analysis of the Xiker Earth Dam During the 2020 Jiashi Earthquake, Northwestern China

open access: yesFrontiers in Earth Science, 2021
The 2020 Jiashi Mw 6.0 earthquake occurred at the Kepingtage fold-and-thrust belt in the South Tianshan front, Northwestern China. The ground shaking caused extensive co-seismic deformation of the Xiker dam in the meizoseismal area.

Experimental Investigation of the Liquefaction Properties and Post-Liquefaction Volumetric Strain of Calcareous Sand in Dredger Fill Site

open access: yesAdvances in Civil Engineering, 2020
In this study, dynamic triaxial cyclic tests were conducted to examine the liquefaction properties and post-liquefaction volumetric strain of calcareous sand from a dredger fill site in the midst of the islands and reefs of the South China Sea.

Incremental model for pore water pressure and its applicability in centrifuge modelling

open access: yesYantu gongcheng xuebao, 2022
The centrifugal model test is an increasingly mature and widely-used physical test method. However, there is few researches on the constitutive relationship, and the researches on the constitutive relationship under the real stress and boundary ...

Liquefaction Resistance of A Partially Saturated Sand

open access: yesSoils and Foundations, 1989
ABSTRACT Cyclic torsional shear tests on hollow cylindrical specimens were conducted to investigate the effects of degree of saturation on the undrained cyclic shear strength (liquefaction resistance) of air-pluviated Toyoura sand at a relative density of 60 percent. The tests showed that (1) the liquefaction resistance increased significantly with a
