## Abstract
Abstract The exposure of highly weathered rocks at the research location will affect the strength of the rock so a geological and geophysics approaches to creating subsurface lithology will make it easier to analyze the bearing capacity of soil in Suppa, Pinrang regency. The research aims to analyze subsurface lithology and soil bearing capacity based on correlations between soil mechanics and geophysics data. Data used in this research are the measurement of vertical electrical sounding (VES) Schlumberger configuration with one track, drilling, laboratory tests (test of shear strength, volume weight, specific gravity, and sieve analysis), and megascopic description of rocks. Terzaghi’s theory on the foundation (continuous, square, and circular) is used for the analysis of soil bearing capacity. Correlation of drill data with geoelectrical data and electrical logging lithology of the study area interpreted at a depth of 0-2.1 m silt sand, 2.1-7.2 m depth of clay, and 7.2-70 m depth of volcanic breccia. The results of the ultimate soil bearing capacity analysis on the first sample of silt sand (continuous, square, and circular foundations, 50-400 m wide) is 147.48 – 427.11 kg/cm2 are classified as very good condition. The second sample with the value of ultimate soil bearing capacity of 72.63 - 109.07 kg / cm2 is classified as a medium - good condition. Based on these results, the first sample has a higher soil bearing capacity than the second sample. Circular foundations have the greatest soil bearing capacity, so a circular foundation is recommended at that location.
