Abstract
The liquefaction potential of sandy and clayey silts is assessed in this paper using an energy approach original developed for sand. Three series of laboratory tests were conducted to examine the liquefaction resistance of clean silt, sandy silt and clayey silt. The test results have been analyzed to establish a liquefaction failure criterion for silty soils. Based on this criterion, the case records of a new database have been studied and the results suggest that a single criterion can be used for sand, silt, sandy silt and clayey silt. For sandy or silty soils without clay content, the criterion is expressed in terms of the earthquake magnitude, hypocentral distance and the corrected standard penetration resistance. For clayey silt, the same criterion and parameters can be used except the standard penetration resistance has to be modified in terms of the clay content.
