Abstract
The MASW field parameters are important for recording surface wave data because they could be affected to the characteristics of dispersion curve. The characteristics of dispersion curve could then be used in obtaining the reliable shear-wave velocity. Therefore, this study aims at determining the optimum field parameters for Bangkok sub-soils. The results show that the MASW optimum field parameters of the Bangkok subsoils are 14-lbs sledgehammer, 10 Hzgeophone and 12 or more number of geophones. Moreover, the minimum offset was 5-10 m and geophone spacing was 1-2 m.
