Cone penetration index for soil behaviour type prediction
Scientific Reports, 2022 Several approaches have been proposed to classify soil types using both cone and piezocone penetration tests. The chart relating the normalized cone resistance (Q tn ) and the friction ratio (F r ) has proven to be the most reliable method.

Predicting soil cone index and assessing suitability for wind and solar farm development in using machine learning techniques. [PDF]
Sci RepThis study proposes a novel approach that combines machine learning models to predict soil compaction using the soil cone index values. The methodology incorporates support vector regression (SVR) to gather input data on key soil parameters, and the ...

Mapping of Cone Index for Precision Tillage [PDF]
Journal of Biosystems Engineering, 2005 Precision tillage is designed to till lands variably according to their firmness. Therefore, it is necessary to measure soil firmness in fields and present it in a form with which the variable tillage on be performed. Such forms may be classified into two categories: sensor-based and map-based forms.
