Abstract
The Spectral Analysis of Surface-Waves SASW method for profiling the subsurface is discussed. The method assumes that the subsurface structures consist of a stack of horizontally homogeneous layers. Variable transient impact source on the ground surface are used to generate Rayleigh waves of different frequencies. From analysis of phase information for each frequency the velosity of the waves is determined between two receivers and combination of results from various receiver spacing were integrated to produce an experimental velocity dispersion curve. Modelling of the dispersion curve was then carried out through an iterative inversion process and the final dispersion curve was then validated. The results were then converted to a soil stiffness profile with depth for applications in geotechnical engineering.
