Relation between Residual Shear Strain Following Liquefaction and Reconsolidated Volumetric Strain

Abstract

Earthquake damage occurs due to residual ground deformation when soil liquefies. The residual deformation consists of lateral spreading and settlement. Few attempts have been made to determine the effect of lateral displacement on settlement following liquefaction. In this study, cyclic loading tests under undrained condition were conducted for clean sand using a hollow cylindrical torsion test and reconsolidation tests were carried out following various residual shear strain applications. It was shown that reconsolidated volumetric strain decreases as residual shear strain increases, with a maximum of 20% decrease in loose sand and 50% in dense sand.
