Multi-channel analysis of surface waves (MASW) using dispersion and iterative inversion techniques: implications for cavity detection and geotechnical site investigation

Most of the surface wave-based geophysical methods require an accurate estimate of the shear wave velocity (Vs) for geotechnical site investigation. The Vs gives a measure of shear modulus which is an important engineering parameter and also owns implications for delineating weak zones and cavities. Geotechnical investigation of such zones is imperative to avoid hazards related to high building construction. Among different surface wave-based...
