Abstract

Recently, the techniques in geotechnical engineering design based on shear wave velocity measurement have had positive effects on the development of Spectral Analysis of Surface Wave (SASW) test. This SASW test has been shown to give reasonable results for in-situ measurements of shear wave velocity. In this study, the used of shear wave velocity and damping is being successfully applied to determine the ultimate pile bearing capacity. The method based on the viscoelasticity soil model proposed by (Abbiss, 1983) and the equation of the relationship between hyperbolic shear strain and shear stress suggested by (Hardin and Drnevich, 1972) has been used in this study. Further, the results from SASW and Instrumented Pile Load (IPLT) test that has been conducted at a site of residual soils located in Damansara, Selangor were compared. The results of the numerical calculation indicate that the percentage error in the ultimate pile bearing capacity is -1%, achieved the standard acceptance in the geotechnical engineering design.
