Resumen
Se presenta en este trabajo un resumen de los resultados obtenidos en los últimos años en la caracterización de distintas estructuras de cimentación mediante georradar, metodología no invasiva que con la combinación de antenas de distintas frecuencias permite conocer el tipo de cimentación superficial (zapata, losa), sus dimensiones en planta y en profundidad, así como los niveles de armadura interna existentes. En el caso de las cimentaciones profundas su aplicabilidad es más limitada, pero en determinadas condiciones, puede suministrar los parámetros geométricos principales. La información así obtenida permite abordar los proyectos de rehabilitación con una mayor seguridad y economía de recursos, al permitir conocer las geometrías de los elementos de cimentación y su variación, sin necesidad de acceder al subsuelo de forma directa o al menos para reducir la caracterización directa o dotar a dichos resultados de representatividad
Abstract
This paper presents a summary of the results obtained in recent years in the characterization of different foundation structures by means of georadar, a non-invasive methodology that with the combination of antennas of different frequencies allows to know the type of surface foundation (zapata, slab) , its dimensions in plan and in depth, as well as the existing internal reinforcement levels. In the case of deep foundations, its applicability is more limited, but under certain conditions, it can supply the main geometric parameters. The information thus obtained allows us to address the rehabilitation projects with greater security and economy of resources, by allowing to know the geometries of the foundation elements and their variation, without the need to access the subsoil directly or at least to reduce the direct characterization or endowing said results with representativeness.
