| 摘要: |
| 采用压力板法测定了非饱和黄土的基质吸力。结果表明，非饱和黄土的水分特征曲线可用幂函数关系描述；吸着水含量与毛细管水含量随基质吸力的增大而减小；基质吸力由吸着力和毛细管力形成。 |

| Abstract: |
| The matrix suction of unsaturated loess was measured with the method of pressure board. The result indicated that the feature curves of moisture content in unsaturated loess could be discribed with power function relation.The water content of attraction and capillary decreased with the increase of the matrix suction, which consisted of attraction and capillary powers. |
| Key words: unsaturated loess, feature curve of moisture content,matrix suction, attraction power, capillary power |
