The phase velocities at frequencies ...Jan 1, 2023 · The MASW test has become a widely practised technique due to its use of multiple channels for data acquisition of surface waves. MASW technique offers high resolution and high signal-to-noise ratio. The Rayleigh waves offer the mode with the highest energy content among different waves produced during impact [ 23 ] and hence is used for the test. Passive multichannel analysis of surface wave (MASW) is a nondestructive technique capable of exploring soil subsurface to a great depth by utilizing ambient long-wavelength passive surface waves without requiring an active source. The method yields subsurface information in terms of shear wave velocity (Vs) profile of the surveyed area. Vs is a vital dynamic property of soil which has ...Aug 1, 2022 · An introduction to MASW for ground investigation.This short webinar will introduce MASW (multichannel analysis of surface waves) as an efficient tool for sit...

The MASW seismic method allows to obtain the shear wave velocity (Vs) distribution in the ground and bedrock. It can be applied as a 1D sounding or as 2D profiles. The MASW method exploits the dispersive nature of the ground. Each frequency component of the surface wave has a different propagation velocity (phase velocity). MASW method consist of Data Acquisition, Dispersion and Inversion analysis. Field Data is recorded in the time-domain from 24 geophones, with the help of seismograph. This is done by hammering near the starter geophone. Filtering of time domain signal is performed for the required frequency range of 3 to 50 Hz to ensure that specified geophone ...
