| 摘 要： | 黄土的湿陷性对于建筑的安全具有极大的危害性，而强夯法可以有效地消除黄土的湿陷性。通过对强夯前后湿陷性黄土的物理力学性质及微观结构进行对比分析，强夯效果沿深度可分为三段，从3 m至8 m为强夯效果最佳段。强夯使土体中孔径大于20 μm的孔隙含量减少，小于5 μm的孔隙含量增加，土体的致密程度提高。

| Abstract: | The collapsibility of loess, which can be effectively eliminated by the dynamic compaction, does great harm to the safety of constructions. The effect of the dynamic compaction is evaluated through the contrast and analysis of the physical and mechanical properties of the collapsible loess before and after dynamic compacting. The compacting effect can be divided into three phases along the depth, and the most effective improved depth is from 3 to 8 m. The content of pores larger than 20 μm decreases and the content of pores smaller than 5 μm increases after the dynamic compaction. The density of loess is improved. |
