Intelligent compaction theory of high roller compacted concrete dam

给出了高碾压混凝土坝智能碾压的概念及实现过程,提出了大坝实时监控和智能反馈控制的原理;在实时分析压实指标的基础上,建立了大坝压实质量多元回归模型,进而提出了碾压混凝土坝压实度全仓面实时评价方法;实现了施工过程中碾压机工作性态的自适应调整,确保碾压机速度、激振力、碾压遍数和压实厚度等全过程达标,可有效保证碾压质量,提高施工效率,为碾压混凝土坝建设质量控制提供了一条新的途径。

In the paper, patted concrete dam construction the concept and realization process of intelligent compaction for high roller comwas 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.
