Abstract: Abstract: Hydraulic sandfill is one of the most popular land reclamation methods. During hydraulic sandfill reclamation process, the losses of fines in reclaimed soil would influence the properties of filled materials. Therefore, it is important to evaluate the effect of hydraulic reclamation process on the dynamics properties of soil. In this study, the reclaimed soil in Yun-Lin area of West Taiwan was obtained as samples. A hydraulic fill sample preparation method is developed to discuss the placement properties of hydraulic reclaimed soil. Various effective confining pressures, consolidation stress ratios and sample preparation methods were discussed. Resonant column tests were performed to evaluate the shear modulus and damping ratio. As shown in the results, the maximum shear modulus (Gmax) of reclaimed soil increased as the confining pressure increased. The Gmax of reclaimed soil specimen prepared by hydraulic sandfill method is larger than Gmax obtained from specimen prepared by moist tamping method. Empirical equations are proposed for maximum shear modulus (G*max) prediction. The results obtained in this study can be helpful for land reclamation design, evaluation and stability assesment.
