Its application range varies, commonly from only a few metres to tens of metres, depending on the wavelengths of the surface waves used for analysis. The output from an MASW survey and analysis is essentially a series of 1-dimensional S-wave velocity profiles, generating spatially discrete data points similar to borehole data. As the data are collected along a line and sampled at closely spaced intervals, it is common to present the data in the form of a 2-dimensional section of S-wave velocities along the survey line, rather than a 1-dimensional profile with depth. If an MASW survey consists of closely spaced survey lines, it is possible to present the output of the surveyed area as a 3- dimensional data set. This paper presents an example of an application of the MASW survey method at a landfill site, with data presented in plan view with a number of depth slices.enCopyright status unknownMultichannel Analysis of Surface Waves (MASW); land fill; compaction monitoring; engineering application; ground improvementConference paper003004054510.1071/aseg2009ab131222635Scott, B.T.
