Abstract
The authors investigate into the mechanism of the occurrence of the liquefaction-induced ground displacement based on case studies during past earthquakes, tests on the characteristics of liquefied soil and on experiments by model grounds, and present fundamental knowledge in order to estimate the magnitude of the horizontal ground displacements. They propose a semi-empirical and semi-theoretical formula for estimation of horizontal displacements of sloped ground, where gradient of ground surface, thickness and N-values of the liquefied soil are taken into consideration as influential factors to the magnitude of the ground displacements.
