对细颗粒含量为21%,23%,25%,27%,29%的混合掺细颗粒砂土试样进行了动强度试验,对三种分层掺细颗粒试样的动强度曲线的分析研究,得出从单层掺细颗粒到两层掺细颗粒,动强度的变化不明显,从两层掺细颗粒到三层掺细颗粒,动强度增加约为3%,对比混合掺细颗粒与分层掺细颗粒,分层的方法效果不明显。

The paper tests dynamic strength of finite particles sandy-soil samples with 21%, 23%, 25%, 27%, 29% content, studies dynamic strength curves of three kinds of finite particles, and finds out that:dynamic strength alteration is not obvious from single-layer to double-layer fi-nite particles, from double-layer finite particle mixture to three-layer finite particle mixture, the dynamic strength increase of about 3%, layer separating method effect is not obvious by comparing finite particle mixture and layer-separating finite particle mixture.
