Abstract

Any particle size distribution can be characterized by two parameter pairs (derived from the statistical entropy formula of discrete distributions) more effectively than simple diameter values (i.e., d50). The first entropy parameter is a continuous internal stability measure. The second one allows the definition of a unique, mean grading curve. In this paper the seismically-induced liquefaction is examined on the basis of the case study of Kobe where gravel and silty sand contained gradings were liquefied. The entropy parameters and the internal stability criterion of the grading entropy theory indicated that the liquefied soils were internally unstable, while other criteria did not indicate possible liquefaction.
