Roller-Compacted Concrete Dams
About this book
ICOLD Bulletin 177 'Roller-Compacted Concrete Dams' presents the state-of-the-art on roller-compacted concrete technology for dams, incorporating the advances of the RCC technology for dams over the last 15 years since the previous Bulletin on the topic was released in 2003. Hence, the present ICOLD Bulletin 177 supersedes ICOLD Bulletin 126 ('Roller-compacted concrete dams - State of the art and case histories', published in 2003) and ICOLD Bulletin 75 ('Roller-Compacted Concrete for Gravity Dams' published in 1989). While roller-compacted concrete technology could have still been considered a new technology in 2003, it is now true to say that construction by roller-compaction has become the standard approach for large concrete gravity dams.
This Bulletin addresses all aspects of the planning, design, construction and performance of RCC in dams. Mixture proportioning and quality control are discussed and a comprehensive listing of references is included. Many aspects of RCC in dams have become better understood since the publication of Bulletin No 126 and the present Bulletin contains less information on the particular approaches applied in different countries, but includes more comprehensive information particularly in relation to design, mixture proportioning and construction. With greater understanding, it has further been possible to highlight more definitively the requirements of successful RCC dams, as well as the pitfalls and difficulties that can be associated with RCC dam design and construction.
Le Bulletin CIGB 177, intitulĂ© « Barrages en BĂ©ton CompactĂ© au Rouleau » prĂ©sente les derniĂšres avancĂ©es en matiĂšre de technologie du bĂ©ton compactĂ© au rouleau pour les barrages intĂ©grant les progrĂšs de la technologie BCR pour les barrages au cours des 15 derniĂšres annĂ©es, depuis que le dernier bulletin sur le sujet a Ă©tĂ© publiĂ© en 2003. Par consĂ©quent, le bulletin 177 remplace le bulletin 126 (« Barrages en bĂ©ton compactĂ© au rouleau - Technique actuelle et exemples », publiĂ© en 2003) et le bulletin 75 (« BĂ©ton compactĂ© au rouleau pour barrages-poids - Technique actuelle » publiĂ© en 1989). Alors que la technologie du BCR pourrait encore ĂȘtre considĂ©rĂ©e comme une nouvelle technologie en 2003, il est maintenant vrai de dire que la construction par le compactage par rouleaux est devenue l'approche standard pour les grands barrage-poids en bĂ©ton.
Ce bulletin aborde tous les aspects de la planification, de la conception, de la construction et de la performance du BCR dans les barrages. Le dosage du mĂ©lange et le contrĂŽle de la qualitĂ© sont discutĂ©s et une liste exhaustive des rĂ©fĂ©rences est incluse. De nombreux aspects du BCR dans les barrages sont mieux compris depuis la publication du Bulletin no 126. Le prĂ©sent bulletin contient moins d'informations sur les approches particuliĂšres appliquĂ©es dans diffĂ©rents pays, mais comprend des informations plus complĂštes notamment en ce qui concerne la conception, le dosage du mĂ©lange et la construction. Avec une plus grande comprĂ©hension, il a Ă©tĂ© possible de mettre en Ă©vidence les exigences des barrages en BCR rĂ©ussis, ainsi que les piĂšges et les difficultĂ©s qui peuvent ĂȘtre associĂ©s Ă la conception et la construction du barrage en BCR.
