Relations between shear wave velocity and related engineering properties of reclaimed soil

Hydraulic sand fill method is the most widely adopted land reclamation method in west Taiwan. In this study, the influence of different fines content on shear wave velocity of reclaimed soil is discussed. The relationship between SPT-N values and shear wave velocity of reclaimed soil in Mai-Liaw region (Taiwan) is evaluated. As shown in the results, for "critical shear wave velocity void ratio" (e(f.c.)) with 10% of fines content, there exists a maximum shear wave velocity. As the fines content exceed 10%, the shear wave velocity would decrease as the fines content increases. The relationships between shear wave velocity, SPT-N value and soil depth is discussed. The results can be presented for soil property evaluation in land reclamation area and coastal area.
