求翻译：本文还阐述了碾压混凝土配合比设计的方法，通过大量的室内试验、施工现场检测，证实了本设计方法即采用经验公式确定水胶比，土工击实法确定单位用水量是较适宜的 。是什么意思？

This article also describes the method of roller compacted concrete mix design, through the construction site of a number of laboratory tests, testing confirms the empirical formula design method that is used to determine water-Binder ratio and soil compaction method to determine the unit of water consumption is more appropriate.
