Offset And Resolution Of Dispersion Curve In Multichannel Analysis Of Surface Waves (Masw)
14th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2001Influence of offset-related parameters on the resolution of dispersion curve in multichannel analysis of surface waves (MASW) surveys is described from the theoretical perspective of the dispersion curve imaging method used during a normal implementation of MASW.

Multichannel analysis of surface waves (MASW)—active and passive methods
The Leading Edge, 2007The conventional seismic approaches for near-surface investigation have usually been either high-resolution reflection or refraction surveys that deal with a depth range of a few tens to hundreds meters. Seismic signals from these surveys consist of wavelets with frequencies higher than 50 Hz.

Multichannel Analysis of Surface Wave (MASW) Method for Geotechnical Site Characterization
Earthquake Engineering and Soil Dynamics, 2005A surface wave method is often used to map shear wave velocity variation of soil with depth. However, measured seismic wave field usually contains such unfavorable waves as higher modes of surface waves, body waves, and ambient noise. These waves can significantly influence results of the analysis if not properly handled. Since the conventional surface

APPLICATION OF MULTICHANNEL ANALYSIS OF SURFACE WAVE (MASW) IN GEOTECHNICS
Zbornik radovaMASW (Multichannel Analysis of Surface Waves) is a non-invasive seismic method used for geotechnical site investigations, developed in 1999 in the USA. Its primary purpose is to assess soil stiffness by measuring the shear wave velocity (Vs) beneath the surface, which is crucial for geotechnical analysis.

The multichannel analysis of surface wave (MASW) method can be an efficient tool for mapping the near-surface shear-wave velocity (Vs). Data acquisition, dispersion-curve imaging and estimations, inversion, and 2D visualization are distinct MASW components.

In the mid-1980s, the surface wave method was initially exhibited as an instrument for the geotechnical engineering field. This non-obtrusive seismic method of multi-channel examination of surface waves is prominently used to draw out the shear-wave velocity profile (variation of soil with respect to its depth).

The geophysical technique known as Multichannel Analysis of Surface Waves, or MASW (Park et al., 1999) is a relatively new seismic characterisation method which utilises Rayleigh waves propagation. With MASW, the frequency dependent, planar travelling Rayleigh waves are created by a seismic source and then measured by an array of geophone receivers ...

In seismic engineering, the dynamic property of the soil is one of the most important aspects in ground response analysis. Dynamic property is significantly affected by local soil deposits. Shear wave velocity (V s) of soil is one of the main parameters in determining the amplification factor on ground surface.
