DETERMINATION OF THE PLASTICITY INDEX USING SLOPE OF FALL CONE FLOW CURVE

This paper presents two simple equations that can be used to compute the plasticity index of soil using the correlation between the slope of the British fall cone flow curve and the plasticity index. The models were developed using British fall cone test results using soils of widely varying plasticity, including commercial bentonite

本文提出了两个简易方程，可借助英国落锥流动曲线（British fall cone flow curve）斜率与土塑性指数（plasticity index）之间的相关性，计算土样的塑性指数。上述模型基于塑性范围跨度广泛的各类土样的英国落锥试验结果开发而成，受试土样涵盖商用膨润土（commercial bentonite）。
