Pilote geotérmico, Comportamiento termo-mecánico, Ensayo a escala realResumo
El artículo se centra en los estudios experimentales sobre el comportamiento mecánico de los pilotes geotérmicos. Se presenta de forma resumida el proyecto español PITERM (2011-2013), sobre un pilote experimental de hormigón prefabricado, hincado en Valencia, y sometido a cargas mecánicas y térmicas, simulando su funcionamiento durante el verano, en modo climatización. Se incluye una breve revisión de pruebas experimentales realizadas en diferentes países, cuyos resultados van al encuentro de los obtenidos en PITERM, confirman el modelo conceptual representativo de un comportamiento termo-elástico, para los niveles de cargas térmicas esperables en las aplicaciones reales, y revelan la importancia del perfil de terreno atravesado y de las condiciones de restricción en pie y cabeza del pilote. Se hace también una pequeña revisión de trabajos experimentales sobre modelos a escala reducida en centrífuga, y se finaliza con algunos apuntes sobre las líneas de investigación más recientes a nivel internacional.
