In the paper, the concept and realization process of intelligent compaction for high roller compacted concrete dam construction was presented, as well as the theory of real-time monitoring and intelligent feedback control. Based on the analysis of real-time compaction index, a multiple regression model of the dam compactness was established and a real-time estimation method of compaction quality of the entire work area for roller compacted concrete dam was proposed finally. The adaptive adjustment of the roller work parameters was achieved, with the speed, exciting force, the rolling pass and the compacted thickness meeting the standard during the entire construction process, and the compaction quality and construction efficiency can be both improved as a result. What's more, the research provides a new way for the construction quality control of roller compacted concrete dam.
