This paper aims to verify the effectiveness of the pile integrity test (PIT) for evaluating the presence of anomaly in short caisson foundation elements, more specifically reinforcement exposure due to an execution problem during concreting. The foundation elements tested belong to the expansion of the structure of an electricity substation in the municipality of Itá, state of Santa Catarina, Brazil. In general, the PIT is not commonly used for caissons, due to the surface irregularities occurring along the shaft in this type of foundation. The obtained results showed that the PIT can promote assertiveness and safety when assessing the integrity of these foundation elements, as later confirmed at the site by excavating the problematic elements and performing visual inspection. Thus, the results may validate the use of the PIT as a tool for optimizing the executive control of cast-in-place foundations, even though a Brazilian technical standard on the use of the low strain integrity test for this purpose is still lacking.

Este trabajo tiene como objetivo verificar la eficacia del ensayo de integridad de pilotes (EIP) para evaluar la presencia de anomalías en elementos de cimentación de cajones cortos, más específicamente la exposición de armaduras debido a un problema de ejecución durante el hormigonado. Los elementos de cimentación ensayados pertenecen a la ampliación de la estructura de una subestación eléctrica en el municipio de Itá, estado de Santa Catarina, Brasil. En general, el PIT no se utiliza habitualmente para cajones, debido a las irregularidades superficiales que se producen a lo largo del fuste en este tipo de cimentación. Los resultados obtenidos mostraron Qya casi salgoue el PIT puede promover la asertividad y la seguridad en la evaluación de la integridad de estos elementos de cimentación, como se confirmó posteriormente en el sitio mediante la excavación de los elementos problemáticos y la realización de una inspección visual. De este modo, los resultados pueden validar el uso del EIF como herramienta para optimizar el control ejecutivo de las cimentaciones coladas in situ, a pesar de que aún no existe una norma técnica brasileña sobre el uso del ensayo de integridad a baja deformación para este fin.
