Penggunaan teknik gelombang permukaan (SASW) dalam kajian geologi kejuruteraan

Surface wave technique is a non-destructive seismic technique that can be used to determine the low-strain dynamic properties of sub-surface. This technique can either be performed on soil or pavement surfaces. By generating and measuring sufrace waves in the field, a dispersion curve of surface wave velocity versus wavelength is constructed. An inversion of the dispersion data was then employed to produce the actual stiffness profile of the site. The test method has potential applications in engineering geology sector. Results from surface wave tests on two different sites of cut and compacted fill terraces are presented. The results from SASW test were then compared to the standard test of the SPT and the pressure-meter tests.
