浅谈“填土有效压实最佳含水区间”在路基施工中的作用

On the Function of the Optimal Water Content Interval for Effective Compaction of Earth Fill in Subgrade Construction

从理论上讨论了土的压实机理以及控制含水量对路基压实效果的重要性 ,提出了“有效压实最佳含水区间”的概念 ,以及如何根据击实曲线来确定“有效压实最佳含水区间”,以提高路基施工的碾压效率 ,加快施工进度。并对以后路基施工提出建议。

In this paper, the compaction mechanism of earth fill and the importance of water content control to subgrade compaction effect are theoretically discussed, the concept of the optimal water content interval for effective compaction is proposed, the method to determine the optimal water content interval for effective compaction on the basis of compaction curve is introduced to raise the roller compaction efficiency in subgrade construction and to speed up the construction progress, and the suggestion on subgrade construction in future is also made.
