ANALYSIS OF THE SUBSURFACE STRUCTURE OF THE LANDSLIDE POTENTIAL AREA BASED ON THE ELECTRICAL AND MECHANIC PROPERTIES OF THE SOIL

Landslides are one of the natural disasters that often occur around the world. The damage caused was in the form of damage to infrastructure to cause casualties. West Java Province is in first place with the largest landslide incident in Indonesia in 2021, one of which is in Jayagiri village, Lem...

The damage caused was in the form of damage to infrastructure to cause casualties. West Java Province is in first place with the largest landslide incident in Indonesia in 2021, one of which is in Jayagiri village, Lembang District, West Bandung Regency. Jayagiri is an area with slope contours of 20 ? 35 0 . Steep surface contours have a greater potential for landslides. Identification of the surface structure of the slope is carried out against two parameters, namely the type resistance and the strength of the soil. In this study, the method used was a geoelectric method to determine the distribution of subsurface resistivity and analyze soil samples. The results obtained found the presence of a slip field on 4 passes. The slip field on the JG-1 with a depth of 3.18 m, the JG-2 with a depth of 6.62 m, the JG-4 with a depth of 7.6 m and the JG-5 with a depth of 6.05 m. The test results of soil samples, obtained soil in a pivoted state with a high moisture content content. Slope stability analysis obtained the security factor on JG-4 is 1,165 in critical state and JG-5 is 2,278 in stable state. text

description Landslides are one of the natural disasters that often occur around the world. The damage caused was in the form of damage to infrastructure to cause casualties. West Java Province is in first place with the largest landslide incident in Indonesia in 2021, one of which is in Jayagiri village, Lembang District, West Bandung Regency. Jayagiri is an area with slope contours of 20 ? 35 0 . Steep surface contours have a greater potential for landslides. Identification of the surface structure of the slope is carried out against two parameters, namely the type resistance and the strength of the soil. In this study, the method used was a geoelectric method to determine the distribution of subsurface resistivity and analyze soil samples. The results obtained found the presence of a slip field on 4 passes.
