The Gumitir Mountain roadway frequently experiences interruptions caused by landslides due to its steep slope gradient, which extends along approximately 24.30 hectares of terrain. The dominant factors contributing to these landslides include slope excavation, slope steepness, and soil texture. This study employs the geoelectrical resistivity method using the Wenner–Schlumberger configuration. The survey was conducted along a 102-meter line with an electrode spacing of 6 meters, consisting of one electrode point. The initial resistivity data obtained from field measurements were processed using Res2Dinv software to generate a two-dimensional (2D) resistivity cross-section illustrating the subsurface resistivity distribution. The correlation between the geoelectrical data and Standard Penetration Test (SPT) values reveals that at depths between 2 and 6 meters, the subsurface layer exhibits low resistivity values ranging from 4.21 to 30 Ω·m with N-SPT values of 4–6 blows, representing soft clayey and silty materials. At depths of 6 to 19 meters, the resistivity values increase significantly to 30–248 Ω·m, with corresponding N-SPT values of 10–30 blows, indicating denser materials such as sandy silt, weathered rock, and tuffaceous layers. These findings empirically confirm a positive correlation between soil resistivity and N-SPT values—lower resistivity corresponds to lower N-SPT (softer soils), while higher resistivity is associated with higher N-SPT (denser and harder strata). This relationship demonstrates the reliability of the resistivity method as a non-destructive approach to estimating subsurface strength and soil hardness.
