Abstract

The paper focuses on the post-triggering behavior of liquefied sand and its implications for evaluations of the engineering effects of liquefaction. While new tools and refinements continue to be developed on the subjects of pore pressure buildup due to earthquake shaking and of liquefaction triggering, these aspects are reasonably well understood and reliable evaluation methods already exist. On the other hand, the response of the liquefied soil after triggering - when most of the engineering effects take place - remains poorly understood. The paper reviews some of the evidence available on post-triggering behavior, with focus on data from the field and from model centrifuge shaking experiments, and discusses implications for the modeling and evaluation of liquefaction. Lateral spreads as well as liquefied sand response near shallow and deep foundations are examined in some detail.
