In the Sosan reclamation land constructed by Hyundai Co,1984, the basic soil test and electric resistivity survey are carried out for the soft grounds around Tee and Kkot islands composed of tuffbreccia, and granite, respectively. The soil of soft grounds are classified as sandy clay(SC) and sandy silt(SM) in the Tee island, and as sandy silt(SM) in Kkot island according to the unified standard classification system. The vertical distribution of the electric resistivity is identified 4 layes with the value 30∼224 Ωm, 3∼59 Ωm, 0.15∼1.5 Ωm, 110∼1280 Ωm(Tee island:112∼122 Ωm, Kkot island:1260∼1283 Ωm), and the layers are interpreted as aeration layer, freshwater saturated layer, seaweater saturated layer, weathered layer, and basement rock respectively. The electric resistivity value decreases with increase of salinity, and pore water and clay mineral content.
