Abstract/Summary Spectral Analysis of Surface Waves (SASW) is a widely used and accepted method in Geotechnical and Civil Engineering applications for estimating material properties in layered structures based on the dispersion characteristics of surface waves. This project aims to extend existing half space theory to analyse layered structures of finite depth. The excitation frequency and signal analysis need to be adapted and optimised to suit the physical properties of the layered structures and associated wave interactions from the layer interfaces. The material properties of the layered substructure can be estimated by evaluating the Rayleigh Wave dispersion characteristics as a function of frequency. Layer thicknesses and the structural integrity of the samples being tested can be interpreted from the averaged dispersion curves. The application of the new SASW tool enables the estimation of the physical properties of concrete and hybrid structures of unknown layer configurations and the detection of damage in structures of known physical dimensions.
