Multichannel analysis of surface waves method for shallow soil profile exploration.
The Journal of the Acoustical Society of America, 2009In order to explore shallow soil properties in a noninvasive manner, a multichannel analysis of surface waves method was employed to obtain soil shear wave velocity profile up to a couple of meters. In the study, an electromechanical shaker operating in a frequency-sweeping mode was placed on the ground to excite Rayleigh waves propagating along the ...

We present a method that utilizes the Multichannel Analysis of Surface Waves (MASW) technique and a standard common depth point (CDP) roll-along acquisition format similar to conventional petroleum exploration seismic data acquisition to construct a vertical section of the near-surface shear (S)-wave velocity field.

Evaluating hazards at salt cavern sites using multichannel analysis of surface waves
The Leading Edge, 2013Subsidence resulting in sinkholes within dissolution mine fields in and around the city of Hutchinson, Kansas, USA (Figure 1) has been reported for more than 90 years. Salt dissolution and the resulting unpredictable upward migration of the dissolution voids can be observed both in proximity to well bores (dissolution mining, brine disposal, and oil ...

Abstract The dispersive characteristics of Rayleigh type surface waves were utilized to estimate shear wave velocity (Vs) profile followed by imaging the shallow subsurface granitic layers in the heart of Hyderabad. The reliability of Multichannel Analysis of Surface Waves (MASW) depends on the accurate determination of phase velocities ...

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 ...
