dc.descriptionAbstract: Data collection and processing methods for most seismic geophysical methods used to characterize engineering sites assume that the ground surface is level and that the sub-surface layers are horizontal and extend to infinity. These assumptions do not apply to some highway sites which exist on embankments or at bridge abutments or foundations. The objectives of the overall program are to examine the effects of complex geosystems (soil-rock-structure) and anisotrophic states of stress on existing databases, and developing the best field system to derive elastic moduli in embankments and obtaining effective dynamic earth pressures. This report summarizes the results of numerical approximations using a new research tool and field measurements to evaluate the effect of sloping ground on the Spectral-Analysis-of-Surface-Waves (SASW) method. The combined results suggest that surface wave measurements can be reliably and accurately made at sloping ground sites with little modification to existing measurement techniques.-
