Caracterización del subsuelo en el barrio el orfanato, municipio de Pamplona, Norte de Santander, mediante la aplicación métodos geofísicos y geotécnicos.

Abstract

This research presents the application of some geophysical and geotechnical techniques, used for the characterization of the subsoil in the neighborhood of El Orfanato, municipality of Pamplona, Norte de Santander (Colombia). The geophysical techniques applied in this study were the Vertical Electric Sounding (SEV), the Seismic Refraction Tomography (TRS) and the Multichannel Analysis of Surface Waves (MASW), for the geotechnical area the technique that was applied for this study was the Standard Penetration Test (SPT), the methodology used was developed in three (3) stages: the field stage that consisted of the survey of two (2) seismic lines, where a topographic survey was carried out, two (2) tests of standard penetration (SPT) to a maximum depth of 3.66 meters, twelve (12) vertical electrical soundings (SEV), for the acquisition of data from seismic refraction tomography (TRS) and multichannel analysis of surface waves (MASW 1D and 2D) are made a laying of two (2) lines of 80.5 meters in length. The data processing stage in which the data acquired in the field stage were processed, through laboratory tests and specialized software. The data analysis and interpretation stage in which the acquired data is correlated, which results in a type D soil profile, which is classified by the National building code (NSR-10), in the The study area shows the presence of inorganic silts and clayey sands, P wave speeds between 270 m / s and 700m / s, S wave speeds between 320 m / s and 360 m / s.
