Abstract: Geophysical techniques including Seismic Refraction and the Multi-channel Analysis of Surface Wave (MASW), were applied to define subsurface conditions and delineate underground anomalies in the southern piedmont geologic region of Atlanta, Georgia. Seismic refraction was performed to identify the approximate rock profile. Surface Waves analysis was used to further characterize the subsurface conditions in the general areas where the Seismic Refraction survey suggested the presence of relatively shallow rocks. This procedure was applied to detect hidden layers or weak zones that might be present under a shallow rock layer. The acquired data was processed using the SiesImager software suite and SurfSeis software. The information gathered was then used to provide guidance for site specific targeted geotechnical testing including soil drilling, rock coring and laboratory testing. This resulted in a cost-effective foundation design for a proposed 2,700 feet long mechanically stabilized earth (MSE) retaining wall at a solid waste facility. The wall was planned in the course of expanding the facility’s capacity.
