COMPUTATION OF SHRINKAGE LIMIT USING THE SLOPE OF FALL CONE FLOW CURVE

This paper presents a model that uses a slope British cone flow curve or plasticity index of soil to compute the shrinkage limit of the soil. The model was developed based on the analysis of 186 Atterberg limits test results collected from the literature. It has been demonstrated that all Atterberg limits, namely liquid limit, plastic limit, and shrinkage limit, can be determined using a British fall cone in a single testing operation.

本研究提出一款土体缩限计算模型，该模型可基于土体英国锥流动曲线斜率或塑性指数进行缩限计算。该模型依托从公开文献中搜集的186组阿太堡界限（Atterberg limits）试验结果分析构建。研究证实，采用英国锥仪（British fall cone）开展单次试验，即可测定全部阿太堡界限，即液限（liquid limit）、塑限（plastic limit）与缩限（shrinkage limit）。
