Concrete Face Rockfill Dams


Book Description

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.

Geotechnical Engineering of Dams


Book Description

This book provides a comprehensive text on the geotechnical and geological aspects of the investigations for and the design and construction of new dams and the review and assessment of existing dams. The book provides dam engineers and geologists with a practical approach, and gives university students an insight into the subject of dam engineering. All phases of investigation, design and construction are covered, through to the preliminary and detailed design phases and ultimately the construction phase. This revised and expanded 2nd edition includes a lengthy new chapter on the assessment of the likelihood of failure of dams by internal erosion and piping.




Dam Breach Modelling and Risk Disposal


Book Description

This proceedings book gathers contributions presented at the First International Conference on Embankment Dams (1st ICED, Beijing, 5–7 June 2020), which was the inaugural conference of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee TC210 on Embankment Dams. The contributions address five themes: (1) case histories on the failure of embankment dams and landslide dams; (2) dam failure process modelling; (3) soil mechanics for embankment dams; (4) dam risk assessment and management; and (5) monitoring, early warning and emergency response. These proceedings offer a unique resource that systematically presents recent dam breaching cases, their social impact, associated risk management strategies, and disposal methods for failed dams. It is an excellent reference guide for dam and levee engineers, flood safety officials, and emergency management agencies.




Dam Engineering


Book Description

Dams and their auxiliary structures are built to provide water for human consumption, irrigating lands, generating hydroelectric power, and use in industrial processes. They are critical structures for continuing life and providing public safety. Construction of a dam is a complicated task that requires sophisticated modern technology and technical expertise. Scientists need to review and adjust their perspectives on designing embankments and their related structures, and compaction and consolidation of fill material, behavior of concrete materials, geotechnical and seismological studies of the dam site, total risk analysis, safety monitoring and instrumentation, heightening, hydrological studies, soil conservation, and watershed management. This book intends to provide the reader with a comprehensive overview of the latest information in dam engineering.




Dam Engineering


Book Description

Dams are critical structures in the sense that damage or breach of even a small dam may cause an unacceptable loss of life and property. Therefore, the safety of dams over the intended lifespan is of utmost importance for unrestricted operation. The basic prerequisites for any safe and successful operation of a dam include state-of-the-art design, experimental investigations of the construction material and properties of the foundation, a refined theoretical analysis of relevant load cases, and high-quality construction. In the past decades, many advancements have been achieved in both construction technologies and design, including those for the prediction of the long-term behavior of dams under various loading conditions. As such, this book examines these advancements with respect to the design, construction, and performance of earth, rockfill, and concrete dams. Over eight chapters, this book provides a comprehensive overview of the latest progress and research in dam engineering.
