Abstract:

The Spectral-Analysis-of-Surface-Waves (SASW) method is an in situ seismic method for nondestructively determining the modulus profiles of geotechnical, pavement, and structural systems. This method requires no boreholes and is performed entirely from the surface of the system being tested. Measurements are made at strains below 0.001 percent where elastic properties of the materials are independent of strain amplitude. The versatility and relatively easy deployment of this method represent two of the strengths of the method. By generating and measuring surface waves in the field, a dispersion curve, a plot of surface wave velocity versus wavelength, is constructed. This dispersion curve is then inverted in the office. Inversion is an analytical process for reconstructing the shear wave velocity profile from the field dispersion curve. Layering and the Young's modulus of each layer are readily obtained from the shear wave velocity profile.
