    Abstract

    Land reclamation using hydraulic sand fills is a method adopted widely in West Taiwan. In this paper, the influence of fines content, void ratio, and effective confining pressure on the measurement of shear wave velocity of reclaimed soil obtained from the reclaimed soil in the Yun-Lin area of West Taiwan is discussed. A “critical s-wave void ratio” (ef.c.) is defined. As shown in the results, for critical s-wave void ratio (ef.c.) with 10% of fines content, there exists a maximum shear wave velocity. As the fines content exceeds 10%, the shear wave velocity decreases. Based on the laboratory and in-situ test, a modification factor (M) is defined. From the results, the modifications factor (M) increases as the soil depth increases. The results presented can be a reference for soil property evaluation in land reclamation and coastal area.
