Acceleration of aging effect of drained cyclic pre-shearing and high temperature consolidation on liquefaction resistance of sandy soils

Abstract

Drained cyclic pre-shearing and high temperature consolidation were discussed and evaluated as acceleration of the aging effect that rise liquefaction resistance of sandy soils. The raised liquefaction resistance characteristics, i.e. repeatability, anisotropy and degree of the liquefaction resistance raising were clarified. The acceleration of aging effect of drained pre-shearing was evaluated to several thousand years of consolidation. The high temperature consolidation was evaluated to thousand times of real consolidation period.
