Development and prospect of roller compacted concrete arch dam

In recent years, the roller compacted concrete(RCC) arch dam has been widely practiced in water conservancy works and the dam scales become more and more larger. At first in this paper, the development status quo of RCC arch dam at home and abroad is introduced. Then taking practical project as example and based on engineering practices from characteristics of RCC material, structural jointing, seepage prevention and construction technology, the current advances of construction technology in RCC arch dam are summarized. Finally, from the aspects of RCC materials, construction technology, development direction as well as simulation computation and analysis, some development tendencies of RCC arch dam are discussed. The summarization of the experience and lessons from the design, construction technology will effectively guide and promote RCC arch dam construction.
