DETERMINATION OF THE SHRINKAGE LIMIT FROM THE BRITISH FALL CONE FLOW INDEX

Determining the shrinkage limit using the mercury or wax method is time-consuming and error-prone. This paper presents a model that uses a British cone flow index to compute the shrinkage limit of the soil. The model was developed based on the analysis of 186 Atterberg limits test results from the literature leading to the formulation of an equation for computing the shrinkage limit of the soil using the British fall cone flow index.采用水银法或蜡封法测定土的收缩限（shrinkage limit）不仅耗时耗力，且易引入误差。本文提出了一种基于英国落锥流动指数（British cone flow index）计算土收缩限的模型。该模型依托文献中186组阿太堡界限（Atterberg limits）试验结果的分析构建，最终推导得到利用英国落锥流动指数计算土收缩限的计算公式。
