Opis

Concrete Face Rockfill Dams presents the state-of-the-art of dam design and construction. This consulting guide presents details and analyses of twenty-eight large CRFD dams worldwide, including the highest dam in the world. Twelve chapters provide specialist information on concepts, designs, technical specifications, construction details, and instrumentation. Both successes and failures that have led to substantial knowledge breakthroughs are discussed. Moreover, attention is paid to the plans for a CFRD dam over 300 meters high. Intended for dam engineers, this illustrated reference volume is also warmly recommended to other engineering professionals working on the design, construction, and operation of dams and related hydraulic structures.
