REAPPRAISAL OF NON-PLASTIC SOILS

In many cases, the liquid limit of the soil can be determined using the fall cone method, yet the soil is reported as non-plastic. This study suggests that if the liquid limit of the soil can be determined using the fall cone method, then soil possesses some plasticity which cannot be quantified using a conventional method of thread rolling. In this paper, the plasticity index of the alleged non-plastic soil is computed using a mathematical model.

在诸多情形下，土壤的液限可通过坠落锥法进行测定，然而土壤却被报告为非塑性。本研究提出，若土壤的液限可通过坠落锥法确定，则表明土壤具备某种塑性，而这种塑性无法通过传统的线滚法进行量化。在本篇论文中，对于所谓非塑性土壤的塑性指数，采用数学模型进行了计算。
