“…The test is repeated a number of times for different geometrical configurations. Crice (2005) acknowledges the usefulness of SASW but suggests that solutions are neither unique nor trivial and that an expert user is required for interpretation. Lo Presti et al (2003) and Soccodato (2003) compared V s derived from SASW with that obtained from other techniques for Pisa clay and Fucino clayey soil respectively.…”

“…Advantages of this method include the need for only one-shot gather and its capability of identifying and isolating noise. Crice (2005) illustrates how MASW survey data can be reliably interpreted by computer software without human intervention. The authors have found that this is only accurate for simple soil profiles.…”

Abstract:The Multichannel Analysis of Surface Waves (MASW) technique, used to determine shear wave velocity (V s ) and hence small strain stiffness (G max ), has recently generated considerable interest in the geophysics community. This is because of the ease of carrying out the test and analysis of the data. The objective of this work was to assess the repeatability, accuracy and reliability of MASW surface wave measurements for use in engineering studies. Tests were carried out at 8 wellcharacterised Norwegian clay, silt and sand research sites where V s had already been assessed using independent means. As well as being easy and quick to use MASW gave consistent and repeatable results and for the clay sites the MASW V s profiles were similar to those obtained from other techniques. Reasonable results were also obtained for the silt and sand sites, with the best result being obtained for the finer silt.This work also confirms that MASW V s clay profiles are comparable to those obtained by correlation with CPT. For these sites there also seems to be a good correlation between normalised small strain shear modulus and in situ void ratio or water content and the data fit well with published correlations for clays.

“…The SASW method uses a single pair of receivers with an impulsive source and should be repeated several times for different soil/geophone configurations. Although the effectiveness of the method has been verified by many researchers, an expert user is needed to interpret the data (Crice [14]). …”

The multi-channel analysis of surface waves (MASWs) method was used to obtain the shear wave velocity variations through near surface (depth < 30 m) and semideep (30 m < depth < 100 m) soil layers in the city of Ottawa, Canada. Sixteen sites were examined to evaluate the capability of the active and passive MASW methods for cases where the shear wave velocity (V s ) contrast between very loose soil (V s < 200 m/s) and very firm bedrock (V s > 2,300 m/s) is very large. The MASW velocity results compared with those of other geophysical approaches, such as seismic reflection/refraction methods and borehole data, where available, mostly confirming the capability of the MASW method to distinguish the high shear wave velocity contrast in the study area. We have found that, of the inversion procedures of MASW data, the random search inversion technique provides better results than the analytical generalized inversion method.

“…The four are: compression wave, called the P-wave, shear wave called the Swave, Rayleigh wave and Love wave. P and S waves are known as body waves; Rayleigh and Love waves are surface waves as shown in Figure 1 [10]. A seismic wave transmits energy by the vibration of soil particles in different directions.…”
