| 摘 要： | 阐述了黄土结构强度的概念和测定方法及其变化规律,并依据其与含水率的幂函数关系以及黄土湿陷系数与含水率的幂函数关系,找到了结构强度与湿陷系数的线性拟合关系,对黄土结构强度与湿陷性的关系进行了分析.结果表明,黄土的初始含水率越大,结构强度越小,湿陷系数也越小;在含水率相同或相近的情况下,黄土的湿陷系数会随着结构强度的增大而减小. |

| Abstract: | The concepts, testing measures and changing rules about the structural strength of loess are described respectively. According to the relationship of power function between structural strength of loess and water content, as well as the collapsibility coefficient and water content, a linearly fitting formula between structural strength and collapsibility coefficient is found out. Furthermore, the impacts of structural strength on the collapsibility coefficient of loess are analyzed. The results show that the value of structural strength and collapsibility coefficient will be smaller when the value of initial water content is bigger. But when the initial water content is same or near, the collapsibility of loess will diminish with the structural strength increasing. |
| Keywords: | loess structural strength water content collapsibility coefficient |
