RESUMEN: Se instrumentó un túnel de transporte público con poca cobertura, construido con máquina tuneladora EPB en suelo blando, para monitorear su comportamiento geotécnico durante la construcción. Se midieron los parámetros que definen la respuesta del suelo, antes, durante y después del proceso constructivo. En este artículo se describe la instrumentación usada para ese fin, así como la implementación de un sistema nuevo de medición. Se muestran las gráficas relevantes. Se midieron las deformaciones inmediatas y se usaron para verificar el proceso de excavación. Con los datos reunidos, se desarrollaron correlaciones para evaluar la influencia del confinamiento en el suelo circundante y para describir el estado de esfuerzos durante el avance de la tuneladora. Se revisaron los asentamientos en edificios cercanos y se relacionaron con el efecto del relleno de soporte. Se incluyen conclusiones relevantes sobre instrumentación y asentamientos.
