Aiming to develop indices for showing the effects of the preloading method on improving liquefaction and to propose a simple method for predicting the improvement effects, repetitive constant volume shear tests were conducted, and various investigations were performed on the overconsolidation effects of sandy soil from the viewpoint of strength against liquefaction. The study showed that 1) compression index Cc is effective for expressing the improvement effects of the preloading method, and 2) the strength against liquefaction of the ground improved using the preloading method can be easily predicted from compression index Cc and overconsolidation ratio OCR.
