Dam Safety Management / Gestion de la Securite des Barrages: Pre operational phases of the dam life cycle / Phases de conception, construction et mise en service
Dam Safety Management is a major concern during the entire lifetime cycle of a dam scheme. This is particularly true for the operational phase of the scheme that represents by far the longest period in its lifetime cycle. Bulletin 154 presented a general approach and concepts to be applied to dam operation. The current Bulletin 175 extends the developed concepts to all phases preceding the operational phase. Many risks associated with the operation of existing dams have their origins in other phases preceding the actual ...

Dam Safety Management is a major concern during the entire lifetime cycle of a dam scheme. This is particularly true for the operational phase of the scheme that represents by far the longest period in its lifetime cycle. Bulletin 154 presented a general approach and concepts to be applied to dam operation. The current Bulletin 175 extends the developed concepts to all phases preceding the operational phase. Many risks associated with the operation of existing dams have their origins in other phases preceding the actual operation. Although there are numerous ICOLD Bulletins addressing technical aspects of planning, design, construction and commissioning of dams, there is not a single Bulletin which covers the subject in a comprehensive manner. The current document is a first attempt to capture all relevant dam safety aspects in all preoperational phases by systematically characterizing the actors involved, their roles, the activities and complex interactions present in different phases of the dam lifecycle. An Overarching Safety Management System is specifically developed that can be applied to all actors involved. La gestion de la s???curit??? des barrages est une pr???occupation majeure pendant tout le cycle de vie d'un projet de barrage. Cela est particuli???rement vrai pour la phase op???rationnelle du syst???me qui repr???sente de loin la p???riode la plus longue de son cycle de vie. Le Bulletin 154 pr???sente une approche g???n???rale et des concepts ??? appliquer ??? l'exploitation des barrages. Le Bulletin 175 actuel ???tend les concepts d???velopp???s ??? toutes les phases pr???c???dant la phase d'exploitation. De nombreux risques associ???s ??? l'exploitation des barrages existants ont leur origine dans d'autres phases pr???c???dant l'exploitation proprement dite. Bien qu'il existe de nombreux bulletins ICOLD traitant des aspects techniques de la planification, de la conception, de la construction et de la mise en service des barrages, il n'existe pas un seul bulletin qui couvre le sujet de mani???re exhaustive. Le document actuel est une premi???re tentative de capturer tous les aspects pertinents de la s???curit??? des barrages dans toutes les phases pr???-op???rationnelles en caract???risant syst???matiquement les acteurs impliqu???s, leurs r???les, les activit???s et les interactions complexes pr???sentes dans les diff???rentes phases du cycle de vie du barrage. Un syst???me global de gestion de la s???curit??? est sp???cifiquement d???velopp??? et peut ???tre appliqu??? ??? tous les acteurs impliqu???s.
