Liquefaction Strength of Sand Materials Containing Fines Compared with Cone Resistance in Triaxial Specimens

Abstract eng:
Innovative miniature cone penetration tests and subsequent cyclic triaxial tests were carried out on sand specimens containing fines both in the undrained conditions. It has been found that one unique curve relating cone resistance and liquefaction strength can be established, irrespective of relative density and fines content. This indicates that liquefaction strength corresponding to a given cone resistance is constant despite the difference in fines content, which differs from the current liquefaction evaluation practice. The results from the tests on the sustained consolidation specimens plotted a little shifted above the unique curve obtained from the tests on the normal consolidation specimens. This may indicate that, if in situ consolidation effect is considered, liquefaction strength for the same cone resistance tends to increase with increasing fines content.
