ANALYSIS OF CONE PENETROMETER LIQUID LIMIT FLOW CURVE USING MATHEMATICAL MODEL

This paper presents a mathematical model which defines the moisture-penetration relationship using British cone. The developed mathematical model gives a unique opportunity of computing or predicting the cone penetration of the soil even at a very low moisture content at which, due to practical limitation it is impossible to determine the soil penetration. The model was found to fit the moisture-penetration data reasonably well. The model was used to compute the penetration of soil at the plastic limit of 394 soils. This study indicates that the plastic limit cannot be defined using one unique penetration value.
