This book provides a timely review on recent advancements in rock-filled concrete dam: a new type of dam originated from Tsinghua University in China. It covers historical overview of the development, filling process of high performance self-compacting concrete, mechanical and physical properties of rock-filled concrete, design of rock-filled concrete gravity dams and arch dams, as well as construction and quality control specifications. The book is intended for researchers, practicing engineers and graduate students who are interested in fundamental research and engineering design principles of rock-filled concrete dams. Successful insights gained from more than 120 rock-filled concrete dams completed or under construction in China are presented in this book, which can be useful references for all readers.
A comprehensive guide to modern-day methods for earthquake engineering of concrete dams Earthquake analysis and design of concrete dams has progressed from static force methods based on seismic coefficients to modern procedures that are based on the dynamics of dam–water–foundation systems. Earthquake Engineering for Concrete Dams offers a comprehensive, integrated view of this progress over the last fifty years. The book offers an understanding of the limitations of the various methods of dynamic analysis used in practice and develops modern methods that overcome these limitations. This important book: Develops procedures for dynamic analysis of two-dimensional and three-dimensional mod...

This book, on the basis of a generalization and critical analysis of materials on constructed concrete dams, accumulated experience in their operation, and current trends, considers a set of problems associated with the design and construction of concrete dams. The modern principles of designing gravity and arch dams and the main provisions of the calculation justification of their reliability in comparison with US standards are outlined. Great attention has been paid to rolled concrete dams, taking into account their specific characteristics. Ways of increasing the efficiency of dams through the improvement of layout and structural solutions, calculation methods, and a more complete conside...
The hazard posed by large dams has long been known. Although no concrete dam has failed as a result of earthquake activity, there have been instances of significant damage. Concerns about the seismic safety of concrete dams have been growing recently because the population at risk in locations downstream of major dams continues to expand and because the seismic design concepts in use at the time most existing dams were built were inadequate. In this book, the committee evaluates current knowledge about the earthquake performance of concrete dams, including procedures for investigating the seismic safety of such structures. Earthquake Engineering for Concrete Dams specifically informs researchers about state-of-the-art earthquake analysis of concrete dams and identifies subject areas where additional knowledge is needed.
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 h...
A book of broad interest to professionals, dam engineers and managers, and to organizations responsible for dam development and management, RCC Dams offers a topical account of the design and operation of roller compacted concrete dams, describing the latest developments and innovative technologies in the field. The book considers planning and design, materials and construction, as well as the operation and performance of RCC dams.
This study was conducted to identify methods that have been used in the repair and rehabilitation of concrete dams. Information was obtained through literary searches, discussions with project personnel, and visits to project sites. Each case history includes a background of the project, the deficiency that necessitated repair or rehabilitation, and descriptions of materials and methods used in the repair or rehabilitation. When available, the cost of the repair project and the performance of the repair to date have been included. Case histories included in this report cover a range of deficiencies in concrete structures, including cracking, spalling, erosion, leakage, inadequate PMF capacity, expansion resulting from alkali-aggregate reaction, instability, and insufficient storage capacity.
