Análisis de estudios geofísicos para la caracterización del subsuelo en la vía Pamplona-Bucaramanga. Zona el Buque, Pamplona (Norte de Santander).

Abstract

In the north-east of Colombia,influenced by the Andean orogeny, in the municipality of Pamplona, there are active faults such as the Tib ´ u-Mercedes formation, Aguardiente and the Chitag ´ a fault of the inverse type with north-south course with strong structural control that geomorphologically Gives origin to hills and blades with presence of igneous metamorphic rocks, which shows predominant formations of coarse grain biotite, plagioclase, quartz and large crystals of pink feldspar. By means of the analysis carried out with the field tests, it is sought to characterize the subsoil geotechnically by the application of seismic refraction studies that measure the velocity of the waves transmitted by the soil substrate, the electrical resistivity tomography that determines the resistivity to the flow Of current that composes a terrain and the test of standard penetration with which it is quantified the load bearing capacity of the terrain and other characteristics product of laboratory tests, to obtain the properties of this, depths of the respective strata and incidence of the present geological faults On the zone for the creation of settlements; The application of each of these methods is intended to be complemented jointly and thus get an establishment will see the characteristics of the subsoil in the slope that is the object of study.
