Les risques lies au vieillissement des geotextiles-filtres utilises dans les ouvrages de drainage sont un enjeu majeur pour l’ingenierie des glissements de terrain et des ouvrages hydrauliques. Le projet DrainAgeing vise a mieux comprendre les phenomenes de vieillissement par colmatage de ces materiaux afin de mieux les prevenir et de formuler des recommandations pour les concepteurs et gestionnaires d’ouvrages. / Risks related to geofilters ageing used in drainage are very important in the context of landslides stabilization engineering and dams and dikes design. “DrainAgeing” research project aims to a better understanding and prevention of drains ageing and clogging. This paper is about the state of progress of the project and the results of 18 years monitoring of Roissard experimental draining trenches. We conclude about the excavation and the analysis of geotextiles and geomaterials recently performed within the context of the second phase of the project.
