|Summary:||The purpose of this study is to develop electrical resistivity models in geological formations of greater interest for geological engineering in the southern area of the East of Cuba. A procedure for the generalization of the geo-electrical databa se was prepared to generate the referred geo-electrical models. A total of 38 works with 895 vertical electrical surveys, of which 317 (35.4%) located near (parametrical) drills. Three models for the Paso Real formation and one for the Capdevila, the most distributed in the region under investigation were defined. The surface quartz sands from the municipality of Sandino were identified to have higher electrical resistivity averages (1241 Ω·m), while they do not exceed 86 Ω·m in the lower horizons to resolve basic tasks of the geological engineering investigations. The assessment of the cover clayey sandy soils was satisfactory in both geological formations while the determination of the water table depth was unfavorable. The remaining tasks varied bet ween relatively favorable to unfavorable according to the geological formations.|
