عنوان انگلیسی Subsurface Characterization in Southeastern Asaluyeh Using DC Resistivity and Ground Penetrating Radar
چکیده انگلیسی مقاله This paper integrates the results of resistivity tomography and Ground Penetrating Radar (GPR) surveys to investigate the structural features of the southestern Asaluyeh site. By combining these geophysical methods with field observations, the study aims to provide a precise interpretation of subsurface conditions, focusing on identifying layer thicknesses, fractures, and weakened zones. The study utilized Direct Current (DC) resistivity and electromagnetic methods, i.e., GPR, both known for their high resolution, rapid data acquisition, and cost-effectiveness. Four DC resistivity and GPR profiles were analyzed where the results show three critical zones of varying layering in the resistivity sections. These zones include the gypsum layer in the marl host and fractures within the marl layer, with depths of influence ranging from 5 to 12 m. The GPR surveys, identified anomalies based on dielectric permittivity differences. The Joint interpretation of DC resistivity and GPR results revealed significant correlations between two methods, enhancing the understanding of subsurface features. Critical zones identified by both methods showed substantial overlap, confirming the presence of subsurface anomalies and providing a comprehensive view of the site's geological conditions. This integrated approach demonstrates the effectiveness of combining DC resistivity and GPR in subsurface investigations, offering valuable insights for similar geotechnical studies.
