Resumen
Caracterización geotécnica de una parcela ubicada en el T.M. de Linares (Jaén). Las técnicas de campo utilizadas han sido: campaña de tomografía eléctrica (ERT) y dos de penetración dinámica tipo Borros. Además, se han realizado ensayos geotécnicos de laboratorio: determinación de la humedad, determinación de los límites de Atterberg, análisis granulométrico y determinación de la expansividad del suelo mediante equipo Lambe. Los ensayos de penetración dinámica nos proporcionan información del terreno en una sola dimensión, en cambio, ERT permite tomar información del subsuelo en dos dimensiones. La campaña de prospección geofísica mediante ERT ha permitido definir la variación de resistividad eléctrica tanto en profundidad como lateralmente del terreno, pudiendo así extrapolar los resultados de los ensayos de penetración dinámica a otros puntos de la parcela. Con los valores obtenidos en los ensayos se ha concluido que, para una futura edificación, el método de cimentación más apropiado será de tipo losa.
Geotechnical characterisation of a plot located in the municipality of Linares (Jaén). The field techniques used were: electrical tomography campaign (ERT) and two Borros-type dynamic penetration techniques. In addition, geotechnical laboratory tests have been carried out: moisture determination, determination of the Atterberg limits, granulometric analysis and determination of the expansivity of the soil using Lambe equipment. Dynamic penetration tests provide us with information about the ground in one dimension, whereas ERT allows us to take information about the subsoil in two dimensions. The geophysical prospecting campaign using ERT has made it possible to define the variation in electrical resistivity both at depth and laterally in the ground, thus being able to extrapolate the results of the dynamic penetration tests to other points in the plot. With the values obtained in the tests, it has been concluded that, for a future building, the most appropriate foundation method will be slab foundations.
