Abstract: 

Having knowledge about elastic prosperities of different layers of Earth has many useful applications in geophysical and geotechnical engineering projects. One of the important parameters in determination of static constants and the key parameter controlling the amplification of seismic motion during earthquake is shear-wave velocity. Because of the dispersive characteristic of Rayleigh waves when traveling through a layered medium and the important role of Swave velocity in determination of Rayleigh wave velocity, dispersion of phase velocity of surface waves can be used for near-surface S-wave delineation. In this study Common Mid Point Cross-Correlation analysis of multi-channel surface-wave data (CMPCC MASW method) is used for dispersion curve determination of 2-D seismic reflection survey data. CMPCC MASW analysis is a further extension of Multi-channel Analysis of Surface Waves (MASW) that improves the accuracy and resolution of MASW by overcoming the problem of improved lateral resolution trading off against accuracy of phase velocity at low frequencies. It also enables Spectral Analysis of Surface Waves (SASW) method to perform a pseudo multi-channel analysis in order to distinguish fundamental mode from higher modes visually and therefore solving the spatial aliasing problem of SASW method.
