Abstract
Recent advances in non-invasive surface wave techniques have led to their increasing use in site characterization studies. This paper compares the results from two different surface wave methods applied to assess the compaction quality of a dynamically compacted site in Western Sydney. The first, the passive Horizontal to Vertical Spectral Ratio (HVSR) method relies on natural (tides, wind, etc.) and cultural (vehicular traffic, trains, etc.) noise sources to generate the HVSR curve which constitutes the basis of this technique. The second, the Multichannel Analysis of Surface Waves (MASW) method relies on an active noise source generated from a sledgehammer hit to the ground (in this study), to generate the phase velocity dispersion curve which underpins this technique. The results from both surface wave techniques were also compared against mechanical CPT and DMT data to verify if consistent estimates of the ground compaction were obtained.
