Recent Enhancement of the RCC Technology in Dam Engineering

摘要

The paper focuses on overview of recent developments of the technology of roller compacted concrete (RCC) dams. It briefly summarizes the evolution of the technology and its early application and presents conceptual changes in major design and construction features which resulted from over forty years of application in different countries. The paper also discusses the future possible extension of application of the technology for appurtenant structures of dams especially for rehabilitation works with respect to the advantages of the RCC. As an example of such application the case of rapid reconstruction of the chute of the Oroville dam which was heavily damaged during spring flood in 2017 is presented.
