Earthquakes have always been a significant aspect of the design and safety of dams. This position paper deals with the seismic safety of large dams, based on experiences with large earthquakes in Japan (Tohoku earthquake, 2011, Richter magnitude 9.0), in China (Wenchuan earthquake, 2008, Richter magnitude 8.0) and in Chile (Maule earthquake, 2010, Richter magnitude 8.8). It presents ways to prevent key aspects of large dam failure under severe seismic conditions with a focus on design instead of on earthquake prediction. This is done by considering the prevention of uncontrolled rapid release of water of a storage dam under full reservoir conditions in relation to expected seismic conditions.This position paper is composed by the Committee on Seismic Aspects of Dam Design of The International Committee of Large Dams.Les tremblements de terre ont toujours ete un aspect important de la conception et de la securite des barrages. Ce document de synthese traite de la securite sismique des grands barrages, en se fondant sur l’experience acquise lors de grands seismes au Japon (seisme de Tohoku, 2011, magnitude 9, 0 sur l’echelle de Richter), en Chine (seisme de Wenchuan, 2008, magnitude 8, 0 sur l’echelle de Richter) et au Chili (seisme de Maule, 2010, magnitude 8, 8 sur l’echelle de Richter). Il presente des moyens de prevenir les aspects cles de la defaillance des grands barrages dans des conditions sismiques severes en mettant l’accent sur la conception plutot que sur la prevision des seismes. Pour ce faire, on examine la prevention d’une liberation rapide et incontrolee de l’eau d’un barrage de stockage dans des conditions de reservoir plein par rapport aux conditions sismiques prevues.Cet argumentaire est compose par le Comite sur les Aspects Sismiques des Projets de Barrages de la Commission Internationale des Grands Barrages.
