In this study, the reclaimed soil in Yun-Lin offshore area in west Taiwan is adopted as testing samples. By moist tamping method, the specimens were prepared with different relative densities and fines contents. A series of cyclic triaxial test was performed to investigate the liquefaction induce deformation and settlement of reclaimed soil under earthquake loading. In order to evaluate the effects of pre- cyclic loading on strength resistance of reclaimed soil, the properties of stress and strain are discussed. Based on one-dimensional consolidation theory, the liquefaction induced volumetric changes can be transformed to evaluate the dynamic settlement of reclaimed soil. As shown in the test results, under same fines content, the settlement ratio decreases as the relative density increases. As for same relative density, the settlement ratio increases as the fines content increases. An evaluation method is proposed and can be used to predict the liquefaction induce dynamic settlement in reclamation area.
