| 摘 要： | 本文分析了非饱和黄土强度的组成和结构强度的来源，给出了结构强度的确定方法，研究了结构强度的变化规律，结果表明：非饱和黄土的结构强度可用其天然结构破坏后所丧失的强度衡量，结构强度与初始含水量间具有幂函数关系；结构强度与不稳定凝聚力具有良好的线性关系；提出了非饱和黄土结构强度终止含水量的概念；给出了非饱和黄土抗剪强度的计算公式。

| Abstract: | The constitution and source of structural strength for unsaturated loess is analyzed. The method to determine the structural strength is proposed and the variation law of strength is studied.It is shown that the structural strength of unsaturated loess can be measured by the strength lost due to destruction, the relationship between strength and initial water content is exponential and the strength is linearly related to unsettled cohesion. The concept of terminative water content is suggested and the calculation formula for shear strength of unsaturated loess is obtained based on the experimental data. |

| Keywords: | unsaturated loess structural strength shear strength water content |
