Grading Entropy Variation Due to Soil Crushing ...

The grading entropy of a soil (S) is derived in terms of the more general concept of statistical entropy. It consists of two terms: the base entropy (S 0), arising from the difference in the width of the statistical cells in the conventional grading curve, and the entropy increment (Δ S).The goal of the research was to study which grading entropy plays the role of the "true" entropy in a ...
