Özet
Residual soil often collapses over bedrock cavities during construction in karst areas. This happens especially when excavation reduces the thickness of the unconsolidated cover beds layer. This phenomenon is exacerbated by the inherent complexities of karst environments. The uncertainty surrounding the depth, size, and geometry of subterranean voids renders detailed geotechnical analysis problematic, thereby complicating risk assessment and mitigation strategies for construction projects in these areas. To overcome the problem of detecting subsurface cavities, this study utilized two-dimensional Electrical Resistivity Imaging (ERI) on Antalya tufa units. Vertical Electrical Sounding (VES), a traditional one-dimensional method for resistivity studies, was also used as a supplementary method in this research. Karst units with cavities are formed by melting primary units with atmospheric waters. These cavities may be filled with clay, water, or air, affecting resistivity values. Studying air-filled cavities is the main purpose of this work. Experimental results were compared with the visual appearance of air-filled cavities; they indicated that air-filled cavities correspond to high resistivity values (~15,000 ohm.m). The ERI method can detect subsurface cavities in terms of its accuracy, resolution, required field effort, and ease of data analysis.
