Ground Subsurface Characterization Using Electrical Resistivity and Cone Resistance Value in Geotechnical Investigation
Detecting subsurface geological structures and features is crucial in geotechnical design to prevent potential hazards in the future. To achieve fast and precise interpretation, efficient testing is required in geotechnical engineering. This study aims to evaluate soil characteristics utilizing electrical resistivity and cone resistance methods to determine soil consistency and resistance to external forces. The parameters employed in this study include electrical resistivity, cone resistance, consistency, cohesion, and total friction. The electrical resistivity value is obtained through geoelectric method field measurements, while the value of cone resistance is acquired through the CPT test conducted in the field. Consistency, cohesion, and total friction are determined by measuring cone resistance. The data analysis indicated that changes in cone resistance value significantly impact soil resistivity value, leading to a consistent interpretation of soil layers. The layer located 6 meters below the surface exhibits consistent stiffness, ranging from very stiff to hard soil. In layers at 9 meters and below, the maximum cumulative resistance of shear stress value reaches 588.31 kg/cm. The electrical resistivity and cone resistance data can be used in conjunction to enhance geotechnical investigations.
