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 pre...

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 t un aspect important de la conception et de la scurit des barrages. Ce document de synthse traite de la scurit sismique des grands barrages, en se fondant sur l'exprience acquise lors de grands sismes au Japon (sisme de Tohoku, 2011, magnitude 9,0 sur l'chelle de Richter), en Chine (sisme de Wenchuan, 2008, magnitude 8,0 sur l'chelle de Richter) et au Chili (sisme de Maule, 2010, magnitude 8,8 sur l'chelle de Richter). Il prsente des moyens de prvenir les aspects cls de la dfaillance des grands barrages dans des conditions sismiques svres en mettant l'accent sur la conception plutt que sur la prvision des sismes. Pour ce faire, on examine la prvention d'une libration rapide et incontrle de l'eau d'un barrage de stockage dans des conditions de rservoir plein par rapport aux conditions sismiques prvues.Cet argumentaire est compos par le Comit sur les Aspects Sismiques des Projets de Barrages de la Commission Internationale des Grands Barrages.
