Index Properties-Based Criteria for Liquefaction Susceptibility of Clayey Soils: A Critical Assessment

The Cooper marl in Charleston, SC, a deep layer of clayey soils approximately 5–21 meters (m) below the ground surface, is generally recognized as nonliquefiable material. Data from field cone penetration tests and laboratory tests of samples taken from the Cooper marl are used to investigate the adequacy of index properties-based criteria for assessing liquefaction susceptibility of clayey soils. In particular, the criterion based on soil behavior type index (I and subscript c) and that based on Atterberg limits are examined. The results show that the Atterberg limits-based criterion adequately reflected the characteristics of the marl, whereas the I and subscript c -based criterion erroneously identified the marl as being liquefiable. A possible reason for the deficiency of I and subscript c and a modification to overcome this deficiency are presented.
