Abstract
The relation between liquefaction-induced reconsolidation volumetric strain and undrained shear loading history are studied by using hybrid online testing technique. Irregular cyclic shear was applied to clean sand specimen prior to reconsolidation test controlling volume strain rate constant. As a result, it was found that an accumulated shear strain is better index to explain liquefaction-induced reconsolidation volumetric strain. Furthermore, the volumetric strain increases with lower relative density, and larger accumulated shear strain. Finally, based on the tests results, an idealized relationship between reconsolidation volume change and effective stress is proposed.
