本文从陕西省化肥厂等几个场地新近堆积黄土层的分布,提出用液限值划分的方法,划分的结果符合工程实测沉降情况,方法简单易行。从土的工程特性看,新近堆积黄土与粗颗粒低液限、高粉粒含量黄土有共同之处。我们还用地基变形计算新参数——弦线模量,对陕化五个工程的沉降和湿陷进行了计算,取得了较满意的结果。 In this paper, the distribution of newly accumulated loess layers from several sites such as chemical fertilizer plants in Shaanxi Province is proposed. The method of dividing the liquid limits is proposed. The results of the division are in accordance with the measured settlements of the project. The method is simple and easy to implement. From the engineering characteristics of soil, the newly accumulated loess has similarities with coarse-grained low-liquid limit and high-content loess. We also calculated the new parameter of the foundation deformation—the string modulus, and calculated the settlement and collapse of the five projects of Shanhua, and achieved satisfactory results.
