In this study, the results by the empirical method(Sawada and Takahashi) for the purpose of evaluating the shear wave velocity in dam core zone were compared with the results of the various field tests(cross-hole test, down-hole test, MASW, seismic reflection survey) conducted in core zone of domestic dam sites and the results obtained by MASW in core zone of domestic seven dam sites. The purpose of this study is to evaluate the applicability of the existing empirical method for estimation of shear wave velocity in core zone to domestic dam sites. From the results of four kinds of field test, for evaluation of shear wave velocity in core zone of the existing dam, in consideration that it is not easy to bore the hole in the core zone of existing dam, surface surveys are recommended as realistic methods. On condition that it is impossible to conduct the field test and it is preliminary investigation, it is recommended that Sawada's low bound empirical equation be used. From the comparison between the results of case studies and those of empirical equation, it is recommended that using the lower bound of empirical formulation by Sawada and Takahashi be available and resonable in case that MASW is not available due to the field condition. |
