Utilización de testificación geofísica en la clasificación geotècnica de las facies detríticas de la cuenca de Madrid

Abstract

This paper sets the relationship between geophysical parameters and geotechnical properties of the detritic materials from the Madrid Basin. The geophysical parameters have been obtained from geophysical logging made in twenty seven boreholes. The geophysical parameters Natural Gamma-ray and Conductivity have been selected in this research due to their direct relationship with some soils index properties (granulometry, plasticity). The regression coefficients obtained in this study justify the possible use of geophysical logging to classify the grounds from a geotechnical point of view
