The aim of this research is based on applying different geophysical methods, Geoelectric Resistivity (Vertical Electrical Sounding “SEV“ and Geoelectric Tomography “TGE“) and Seismic Method (Seismic Refraction “RS“ and Multichannel Analysis of Surface Waves “MASW“), the results obtained will determine the geotechnical parameters in the study area and correlate with a geological section in Quebrada Seca, located in La Capilla district, General Sánchez Cerro province in Moquegua Department. The methodology to be used for the research is: first to take topographic, geophysical and geological data, then in the cabinet these data will be analyzed, processed and interpreted and make the correlation (comparison) of the geophysics results with a geology section. In addition, determine the geotechnical parameters from the seismic refraction data (body waves “Vp“), MASW (shear waves “Vs“) and the density of the materials obtained in laboratory tests. The data analysis was carried out comparing different geophysical methods (electrical and seismic) and the correlation with geology. Geological characterization allowed determining the most important geomorphological, stratigraphic and structural characteristics of the study area and mainly finding 4 lithological horizons that correspond to Pleistocene (recent Quaternary) underline to Fm. Labra. Through the application of the TGE, the horizons corresponding to the pleistocene are clearly visible and that below this is the Fm. Labra, this correlates with the horizons found with the geological mapping, while in the SEVs both are correlated and a pseudo resistivity section is constructed, in the strand 3 geoelectric horizons are obtained from the resistivities which correlates with the horizons and the sedimentary rock of the Fm. Labra. The RS method allowed to determine the characteristics of the materials from the speed of the compressional waves (Vp) and the 3 horizons or layers were obtained and for its correlation with the geology tables of different authors were used (Tables 10 to 15) , while with MASW the speed of shear waves (Vs) was determined and in correlation with the geology and interpretation of the soil type according to the IBC tables and the Peruvian Standard E-030 (Tables 8 and 9) with which it is determined 3 seismic horizons and with soil types B and C. The geotechnical (dynamic) parameters of the horizons or subsoil layers were calculated, all calculations were made based on RS, MASW and density values, as shown in Tables 31 and 32, which may be used by civil engineers and geotechnical to carry out future constructions or foundations. It should be noted that all geophysical methods have been correlated with geology.
