Evaluation of reliquefaction resistance using shaking
Evaluation of reliquefaction resistance using shaking

Test results demonstrate that the number of cycles required to trigger liquefaction during the 1st shaking event at any depth is considerably larger than that required to trigger liquefaction during the 2nd event ie reliquefaction likely as a result of the “aged” sand fabric developed during secondary compression of the initially loose sands and the initially anistropic sand fabric resulting from initial deposition
