La termoactivación de estructuras de contención de tierras para su uso como intercambiador de calor en sistemas geotérmicos de baja temperatura, proporciona más eficiencia y menos emisiones de carbono que otros sistemas de calefacción y refrigeración convencionales. Las consecuentes variaciones de temperatura producen una interacción suelo-estructura que debe ser evaluada para garantizar que no se compromete ni la estabilidad ni el servicio, a la vez que se mantiene un rendimiento energético que garantiza la viabilidad económica. En este trabajo se analiza, mediante modelado numérico, el efecto de la termoactivación de las pantallas de pilotes un falso túnel urbano de casi 3 kilómetros en la ciudad de Madrid. Para el análisis de la interacción suelo-estructura se han utilizado datos climáticos reales. Los resultados muestran que, operando en un rango de temperaturas tal que se mantiene el rendimiento de la bomba de calor, el efecto estructural es muy limitado.
