摘要: 采用单位体积击实功相同,但单击功不同的三种击实标准,对土样进行试验,分别测出击实土样的每层层厚、含水率、密度以及干密度,从而得到不同单击功下土样的击实曲线以及密度的变化规律,进而反映出击实能对土体密实度的影响规律,可对现场压实中击实能的选择提供相应的参考建议。

关键词: 击实能, 击实曲线, 密度

Abstract: By conducting compaction test with three different compaction standards, the compaction properties of a typical soil were studied. Three compaction standards have the same total compaction energy per unit volume but with different single compaction work. The compaction curve and change of the density of soil sample were obtained by measuring thickness, moisture content, density and dry density of each layer. Finally, the effect of the compaction energy on the result of compaction test was obtained.

Key words: Compaction Energy, Compaction Curve, Density
