Caracterización geofísica del subsuelo mediante las técnicas de refracción sísmica, reflexión sísmica, MASW y REMI en depósitos superficiales y zonas críticas de la Universidad de Pamplona.

Abstract

The methods applied for the subsoil’s characterization of the study areas were Seismic refraction, Seismic reflection, Multichannel Analysis of Surface Waves (MASW) and Refraction Microtremor (ReMi). This research was developed in five zones situated in the University of Pamplona, which have a total area of 480m, where was made the design of every line in order to establish the distance between geophones and the source location. Once realized the design of the seismic lines and the data acquisition, the p rocessing of the same ones is carried out by means of the programs SeisImager by the company Geometrics and Seismic Unix (CWP), obtaining this way profiles 1D and 2D of every zone. Across the profiles obtained of wave P and S it is possible to estimate the number of caps with their thicknesses and the type of present material in the subsoil with its respective speeds In addition the parameters of the subsoil such as: the bearing capacity, Poisson module, rigidity module, Young module, density and others. W ith the obtaining of the parameters abovementioned a possible response is given to explicate the present faults in the critical zones that were studied.
