Residual deformation property of liquefied soil and related phenomena

Research output: Contribution to conferencePaperpeer-review

Abstract

It is necessary to evaluate the residual deformation property of the liquefied soil appropriately to predict the damage caused by liquefaction quantitatively. To do so, it is necessary to understand there are degrees of liquefaction, and that both ductility and toughness need to be taken into consideration. To evaluate the degree of liquefaction in this study, our attention was on the dilatancy ratio and the drainage water volume obtained from a reconsolidation test after undrained cyclic shear test. These indexes have been shown to be good material performance indexes useful in the evaluation of the residual deformation potential after liquefaction. In this paper, the infiltration destruction mechanism due to the migration of the pore water after liquefaction is introduced, and the effectiveness of both the density increase method and the drainage method is discussed. Finally, the experimental results are applied to the boundary value problem to determine the deformation properties of soil.
