标准摘要
[中文适用范围]： 本文件规定了土壤液限和塑限的测定方法。 这些包括土壤的两个阿特伯格极限。 液限是土壤从液态转变为塑性状态时的含水量。 本文件描述了天然土壤样本或已去除大于约 0.4 毫米材料的土壤样本的液限的测定。 本文档描述了两种方法：落锥法和卡萨格兰德法。 注：本文件中的落锥法不应与 ISO 17892-6 中的落锥法相混淆。 土壤的塑性极限是土壤进一步干燥时不再具有塑性的含水量。 塑限的测定通常与液限的测定一起进行。 人们认识到，测试结果取决于操作者的判断，并且结果会发生一些变化。 [外文原描述]： This document specifies methods for the determination of the liquid and plastic limits of a soil. These comprise two of the Atterberg limits for soils. The liquid limit is the water content at which a soil changes from the liquid to the plastic state. This document describes the determination of the liquid limit of a specimen of natural soil, or of a specimen of soil from which material larger than about 0,4 mm has been removed. This document describes two methods: the fall cone method and the Casagrande method. NOTE The fall cone method in this document should not be confused with that of ISO 17892‑6. The plastic limit of a soil is the water content at which a soil ceases to be plastic when dried further. The determination of the plastic limit is normally made in conjunction with the determination of the liquid limit. It is recognized that the results of the test are subject to the judgement of the operator, and that some variability in results will occur.
