Intelligent compaction theory of high roller compacted concrete dam

摘要

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