针对宁夏黄土分布广泛,含盐量高,结构性强,黄土地基问题日益突出的情况,以干密度、含水率、含盐量为因素,设计L9(34)正交试验方案,应用三轴仪进行无侧限抗压强度试验,分析研究各因素对黄土结构性强度及结构性参数的影响规律。结果表明:黄土的结构性强度随干密度、含盐量的增大而增大,随含水率的增大而减小;无论含水率高低,易溶盐都是影响黄土结构性的重要因素之一。
Considering the wide distribution of loess in Ningxia, high salt content, strong structure and increasingly prominent problems of loess foundation, the L9 (34) orthogonal experimental scheme was designed based on dry density, water content and salt content. Unconfined compressive strength tests were conducted to analyze the influence of various factors on the structural strength and structural parameters of loess. The results show that the structural strength of loess increases with the increase of dry density and salt content, and decreases with the increase of water content. Ease of soluble salt is an important factor affecting the structural properties of loess, regardless of the water content one.
