文摘

Aging effect on liquefaction largely depends on fines content and plasticity index. Plasticity index is more influential than fines content to liquefaction evaluation. For gravels, strain considered in design greatly differs post-liquefaction strength. Inclusion of non/low-plastic fines reduce sand dilatancy under initial shear stress. Water films cause delayed flow failure in layered sand even on dilative side of SSL.
