Abstract
AbstractThis paper summarizes 12 cases of Holocene liquefaction in Pleistocene deposits reported in the literature and reviews nine proposed relationships for estimating the effect of aging on soil liquefaction resistance. The 12 cases are from Argentina, China, Israel, Lithuania, Republic of Karelia and the USA. The nine relationships for estimating the effect of aging are based on laboratory test results, laboratory and field test results, or field test results and ground behavior observations. Because aging processes in soil depend on many factors (e.g., grain size distribution, grain shape, mineral composition, groundwater chemistry, stress history), time is sometimes not a good predictor of the aging effect in liquefaction assessments for engineering projects. Combining small-strain shear wave velocity and larger-strain penetration resistance provides a more robust predictor of the aging or diagenesis effect than using time as the predictor variable.KeywordsAgingDiagenesisLiquefaction
