Expansive clays, Moisture content, Swelling potentialResumen
Los cambios volumétricos inducidos en suelos arcillosos expansivos debido a variaciones en su contenido de humedad han generado daños estructurales significativos en diversos países, y Chile no ha sido una excepción en este aspecto. Usualmente las primeras estimaciones del potencial de expansión se realizan en base a información relativamente limitada, previo al desarrollo de una campaña geotécnica más completa. Como alternativa a esta última se propone aquí un método sencillo que cuenta con una amplísima base experimental para predecir el hinchamiento de estas arcillas al aumentar su humedad, pudiendo incluso llegar a saturarse el suelo que es la situación eventual más crítica. A modo de ejemplo de utilización de este simple método se incluye en este artículo su aplicación al cálculo del movimiento vertical de una cimentación corrida, típica, en uno de los sitios investigados.
