Abstract

In the city of Ica—Peru, there are no data on dynamic soil properties. Therefore, correlations not corresponding to the soil characteristics of this city are currently being used for that purpose. In this study, for determining the dynamic soil properties, accelerograph records and the P-S suspension logging system were used to measure the (P) compressional-wave and (S) shear-wave seismic velocity of deep soil. For this last survey, a 42-m deep well was drilled, and soil with sand and silt was found. In this research, results obtained from the PS suspension records have been compared with the geophysical MASW, MAM, and seismic refraction surveys, the PS-logging being the most accurate technique for determining the velocity of the S and P waves. The values obtained from the shear waves are within the range of 200 m/s to 600 m/s. Likewise, from the accelerograph records, microtremors, and theoretical ellipticity of Rayleigh waves, two predominant periods have been found: T = 0.63 s and T = 3.1 s. Therefore, the shear wave velocity profile has Vs30 = 276 m/s and is classified as type D, according to the ASCE 7–16-2016 standard.
